GLOSSARY

Agriculture data

Fruit and Vegetables - The split between Litchfield, Alligator, Finniss and Daly SSDs is based on tree count or area under cultivation rather than actual value.

Australian Standard Classification of Occupations (ASCO)

Australian Standard Classification of Occupations (ASCO), Second Edition 1997 as published by the Australian Bureau of Statistics (ABS). 'Permanent Overseas Arrivals and Departures' has been classified using the ASCO.

There are three supplementary groups defined by the Department of Immigration and Citizenship that are not included in the ASCO classification. These are:

• 'Not in Employment' refers to persons who have stated that they have been unemployed without providing an adequate occupation description.
• 'Not in Labour Force' includes children, persons stating 'home duties' as their occupation, students and retired persons.
• 'Not Stated' refers to those persons whose occupation description is not sufficiently specified to enable the allocation of precise ASCO codes.

Average annual growth rate

The average annual rate of population growth, r, is calculated as a percentage using the formula below, where is the population at the start of the period, is the population at the end of the period and n is the length of the period between and in years.



Births

Birth - Births are allocated to a Statistical Local Area according to the usual residence of the mother, irrespective of the state or territory in which the birth was registered.

Indigenous birth - An Indigenous birth is the birth of a live-born child where either the mother or the father was identified as being of Aboriginal or Torres Strait Islander origin on the birth registration form. There is an undercoverage of Indigenous births in most states and territories. Therefore, measures of Indigenous fertility and mortality are likely to be conservative estimates. Given the volatility in measures of Indigenous fertility and mortality, caution should be exercised when assessing trends over time.

Total fertility rate - The total fertility rate is the sum of age-specific fertility rates and represents the number of children a female would bear during her lifetime if she experienced current age-specific fertility rates at each age of her reproductive life.

Building data

Building approvals - Statistics of building work approved are compiled from:

• permits issued by licensed Private Building Certifiers or the Building Branch, Northern Territory Department of Planning and Infrastructure, in areas subject to building control by those authorities;
• contracts let or day labour work authorised by Commonwealth, state, semi-government and local government authorities; or
• major building approvals in areas not subject to the normal administrative approval processes (e.g. building on remote mine sites).

Building work approved includes the construction of new buildings, alterations and additions to existing buildings, approved non-structural renovation and refurbishment work and approved installation of integral building fixtures.

Building completions - Statistics of building activity are compiled from the ABS Building Activity Survey. A building is defined as completed when building activity has progressed to the stage where the building can fulfil its intended function.

House - A house is a detached building primarily used for long term residential purposes. It consists of one dwelling unit. For instance, detached granny flats and detached dwelling units (e.g. caretaker’s residences) associated with a non-residential building are defined as houses. Also includes cottages, bungalows and rectories.

Non-residential building - A non-residential building is primarily intended for purposes other than long term residential purposes.

Other residential building - Defined as a building other than a house, primarily used for long-term residential purposes such as a townhouse, flat, unit or apartment. Other residential buildings are coded to the following categories: semidetached, row or terrace house or townhouse with one storey; semidetached, row or terrace house or townhouse with two or more storeys; flat, unit or apartment in a building of one or two storeys; flat, unit or apartment in a building of three storeys; flat, unit or apartment in a building of four or more storeys; flat, unit or apartment attached to a house; other/number of storeys unknown.

Public Housing - The statistical subdivision (SSD) in which an applicant submits a public housing application is used to measure the demand for housing in that area regardless of where the applicant wishes to live.

Climate

Annual average rainfall - Average is based on the period since records have been collected (Darwin Airport 1941; Nhulunbuy DTW 1974; Katherine Aviation Museum 1943; Tennant Creek Airport 1969 and Alice Springs Airport 1941) up to and including 2007-08.

Wet season rainfall - Average is based on the period since records have been collected (Darwin Airport 1941; Nhulunbuy DTW 1974; Katherine Aviation Museum 1943; Tennant Creek Airport 1969 and Alice Springs Airport 1941) up to and including 2004-05.

Commercial Vessel Registrations and Marine Qualifications

Commercial Vessels - All commercial vessels operating within Northern Territory waters are required to comply with survey and safety manning requirements under the Northern Territory Marine Act and Regulations. Vessels are required to hold a valid certificate of survey. Certificates of survey issued by other marine authorities may be accepted for operations in NT waters. Such vessels are still required to complete an Application for Survey.

Class 1- Vessel carrying more than 12 passengers

Class 2- All commercial vessels which are not class 1 or 3. e.g. Charter boats carrying up to 12 passengers, dredgers, work boats, police boats and cargo ships.

Class 3 - Commercial fishing vessels, catching or assisting in catching fish for sale.

Marine Qualifications - Persons in charge of either the navigational watch or the machinery, or of both functions, on a commercial vessel are required by the NT Marine Act to hold an appropriate Certificate of competency. The following vessels are exempt from the above requirements (and as such operators of such vessels may not be represented in the data presented):

• Vessels not more than 5 metres in length, carrying not more than 4 persons, including crew, and operating in designated 'sheltered waters' and inland waters.
• Fishing vessels less than 6.2 metres in length operating in conjunction with a mother vessel and within 5 nautical miles of the mother vessel.
• Fishing vessels less than 6.2 metres in length operating within 5 nautical miles of the coast.

These certificates may be issued by the NT Marine Authority, though certificates issued by other authorities may be recognised as equivalent. Persons holding such certificates are still required to apply for NT recognition.

Concordance

Disclaimer: The concordance product is based on the postcode to SLA concordance created by the Small Area Population Unit, Australia Bureau of Statistics, for the purposes of converting population indicator data. While care was taken in producing this concordance, it is not an official ABS product, and the ABS will not guarantee the accuracy of the concordance. No liability will be accepted by the ABS for any damages arising from decisions or actions based upon this concordance.

Deaths

Death - Deaths are allocated to a Statistical Local Area according to the usual residence of the deceased, irrespective of the state or territory in which the death was registered.

Indigenous death - An Indigenous death is the death of a person who is identified as being of Aboriginal and Torres Strait Islander origin on the death registration form. There is an undercoverage of Indigenous deaths in most states and territories. Therefore, measures of Indigenous fertility and mortality are likely to be conservative estimates. Given the volatility in measures of Indigenous fertility and mortality, caution should be exercised in assessing trends over time.

Standardised death rates - Standardised death rates allow comparison of death rates between populations with different age structures by relating them to a standard population. The current standard population is all persons in the 2001 Australian population. The standardised death rate is the overall death rate that would have prevailed in the 2001 population if it had experienced at each age the death rates of the population under study.

Department of Veterans' Affairs

Department of Veterans' Affairs pensions are listed below:

Disability Pension - A compensation payment for injuries or diseases caught or aggravated by war service or certain defence services performed on behalf of Australia. The amount paid is dependent on the level of incapacity suffered as a result of the war-caused or defence-caused injuries and diseases.

Veteran Service Pension - A means-tested payment that can be paid to veterans on the grounds of age or invalidity. It is payable to males aged 60 years or over while the age at which a female may qualify depends upon her date of birth. Eligibility is also subject to Australian residency requirements.

Partner Service Pension - A payment to eligible partners, widows or widowers of veterans who are receiving or are eligible to receive the Service Pension. It is payable to males aged  65 years and over while the age at which a female may qualify depends upon her date of birth.

War Widow(er) Pension - A pension that is paid to compensate widowed partners of veterans who have died as a result of war service or eligible defence service. War widow(er) pensions are not affected by other income except from other compensation payments.

Further information is available from the Department of Veterans' Affairs website.

Education

Teaching staff - Teaching staff includes all classroom and executive teachers (e.g. principals, full-time and part-time teachers, exchange and visiting teachers, resource teachers, teacher librarians, assistant teachers, part-time instructors, student counsellors, teachers employed through the Community Development Employment Projects (CDEP) Program, and other 'Commonwealth employed' staff that are not under the jurisdiction of the Chief Executive Officer of the NT Department of Employment, Education and Training.

Total number of teaching staff - The actual number of teaching staff, including full-time and part-time staff.

FTE of teaching staff - Full-time equivalent (FTE) of teaching staff numbers, calculated by adding the FTE of full-time staff and the FTE of part-time staff (part-time FTE is calculated as a proportion of full-time FTE).

Student enrolment - The total number of students officially enrolled on the collection date and who have attended school within a four week period preceding the collection date. Students are allocated to a region based on the postcode of the location the student nominates as his or her permanent home residence.

FTE of student enrolment - FTE is the full-time equivalent of student enrolment numbers. It is calculated by adding the FTE of full-time students and the FTE of part-time students (part-time FTE is calculated as a proportion of full-time FTE).

Student enrolment by level - 'Year' is not necessarily the number of years the student has been at school but is a measure of their level of education.

Primary Special - Students who have been panelled through Student Services as having special needs, sensory impaired students, high support needs students, and students attending special purpose schools.

Ungraded Secondary - Students who are aged  12 years or over and undertaking a Special Category Curriculum and includes students in Secondary Support Units (i.e. Aboriginal/Indigenous Units, Secondary Indigenous Education Units).

Secondary Special - Students who have been panelled through Student Services as having special needs, sensory impaired students, high support needs students, and students attending special purpose schools.

Estimated Resident Population

The Estimated Resident Population (ERP) is the official ABS estimate of the Australian population which is based on the concept of usual residence. The ERP for 30 June 2006 is based on the results of the 2006 Census of Population and Housing held on 8 August 2006. It is calculated by adjusting Census counts by place of usual residence by:

• adding the estimated net Census undercount and Australian residents estimated to have been temporarily overseas at the time of the Census;
• subtracting overseas visitors in Australia at the time of the Census; and
• adjusting for births and deaths and interstate and overseas migration during the period 30 June to  8 August 2006.

The ERP for the June 2007 estimates are obtained by adjusting the ERP at 30 June 2006 using the numbers of births and deaths and estimates of interstate and overseas migration for the period between 30 June 2006 and 30 June 2007.

To meet the demand for accuracy and timeliness there are preliminary, revised and final estimates of the resident population. Preliminary estimates are available seven months after the reference date, revised estimates are available a year later, and final estimates are available after each Census for the preceding intercensal period. The estimates in this publication are preliminary for ERP data from September quarter 2005 to June quarter 2006 (inclusive), revised for ERP data for September quarter 2001 to June quarter 2004 and final for all ERP data up to and including June quarter 2001.

Government employee housing

Housing provided through the Government Employee Housing (GEH) program, which is a service through Territory Housing that provides accommodation for eligible Northern Territory Government employees.

Grocery Price Survey

Background - In response to a recommendation of the 1999 Legislative Assembly Select Committee on Northern Territory Food Prices, NT Treasury implemented a Grocery Price Survey that measures the cost of an average basket of goods at selected supermarkets across the NT.

Series Two - A review conducted in 2005 resulted in the surveyed basket being updated (from Series One to Series Two), consistent with changing consumer expenditure patterns. Series Two data has been collected since December 2005, however, the 2007 survey is the first reporting of Series Two data, as Series One is no longer collected. All the data that appears in this publication is Series Two. Since the new survey introduced a break in the series, Series One and Two can not be directly analysed.

Coverage and frequency - The basket comprises 136 items including food (except takeaway), household supplies and personal care products (excluding pharmaceuticals), and is weighted to reflect typical weekly household purchasing patterns. The survey is conducted on a six-monthly basis at supermarkets in Darwin, Alice Springs, Katherine, Yulara and Nhulunbuy. To allow comparison to be made with urban areas of similar size to Darwin and Alice Springs the survey includes Queensland supermarkets in Cairns and Mount Isa.

Data presented - To ensure supermarkets cannot be identified the ABS has provided the averaged price of the standard baskets of goods for the surveyed supermarkets in that region.

Further information can be found in the Grocery Price Survey Technical Paper .

Hospital separations

Separation - Separation is the term used to refer to the episode of care, which can be a total hospital stay (from admission to discharge, transfer or death) or a portion of a hospital stay beginning or ending in a change of type of care (e.g. from acute to rehabilitation). 'Separation' also means the process by which an admitted patient completes an episode of care by being discharged, dying, transferring to another hospital or changing type of care.

Weighted separation - An average measure of resource consumption using admitted patient episodes in hospital.

Imports and exports

Imports and exports are classified according to the 2006 Australian and New Zealand Industry Classification (ANZSIC) (cat. no. 1292.0).

Labour force data

DEEWR small area labour force estimates - The Department of Education, Employment and Workplace Relations (DEEWR) has implemented a procedure for deriving small area labour market estimates, based on the Structure Preserving Estimation (SPREE) methodology. The purpose of SPREE is to produce estimates that reflect the regional disparities of Centrelink data, while being consistent with ABS Labour Force Survey estimates. There are two assumptions made in applying the SPREE methodology. First, it is assumed that recipients of unemployment benefits are uniformly distributed within postcodes. Second, it is assumed that there have been no changes to postcode and SLA boundaries since the 2001 Census of Population and Housing. The reliability of these estimates compared with the Census estimates has been found to vary with the size of the population in small area regions, and these estimates should be treated with caution.

Labour force status - Identifies whether a person aged 15 years or over is employed, unemployed or not in the labour force.

Employed - Includes those people who, during the reference period, worked for payment or profit, who had a job from which they were on leave or were otherwise temporarily absent, who were on strike or stood down temporarily or who worked as unpaid helpers in a family business. CDEP participants are classified as employed.

Unemployed - Includes people who did not have a job but were actively looking for work (either full-time or part-time) and were available to start work.

Not in the labour force - Includes people aged 15 years or more who were not employed or unemployed as defined above. This category includes people who were retired, pensioners and people engaged in home duties.

Labour force participation rate - Is the number of persons in the labour force expressed as a percentage of the population aged 15 years and over. The participation rate is calculated excluding persons who did not state their labour force status.

Unemployment rate - The unemployment rate is the number of unemployed people expressed as a percentage of the labour force.

Law and Justice

Apprehension - Apprehension incorporates all recorded law enforcement action against a person for suspected unlawful acts. It includes enforcement action by way of arrest and summons. The statistics are generated by counting the number of apprehension reports. Many factors can influence crime statistics such as changes in the age composition of the population, legislation, police enforcement practices and reporting by the public to police.

Criminal cases lodged and finalised - Lodgements are counted at the case level when a case has more than one offence associated with it. The defendant is only counted against the most serious offence which may include offences such as breach of justice order (e.g. breach of bail, parole or domestic violence order), subverting the course of justice, possessing or supplying contraband within prisons and failure to lodge tax.

Defendants adjudicated, Supreme Court - Defendant cases judged or decided upon by the Supreme Court as to whether or not the defendant is guilty of the charge(s) laid against them.

Drug Infringement Notices - Drug infringement notices are summarily imposed fines that may be issued by Police for the possession or cultivation of cannabis for personal use only. A penalty of $200 is payable for an offence issued with a drug infringement notice.

Finalisations - An offence is considered to be finalised on the first date that the court makes an order that implies a definite finding of guilt. When a court order is appealed, the offence is not counted as finalised until the appeal is decided.

Geography - Data in tables 7.1, Offences Reported to Police by Selected Regions is presented for the Northern Territory as a whole, six major urban centres and the Northern Territory balance (areas outside of the six major urban centres):

• Northern Territory
• Darwin
• Palmerston
• Alice Springs
• Katherine
• Tennant Creek
• Nhulunbuy
• Northern Territory balance

All remaining data for chapter 7 is presented according to ASGC 2006.

Juvenile apprehension - Refers to all recorded law enforcement action against a juvenile for suspected unlawful acts. Since 1 June 2000 'juvenile' has been defined in the NT as a person aged 10-17 years. Prior to 1 June 2000 'juvenile' was defined as a person aged 10-16 years.

Offence - An offence is an act considered prima facie to be in breach of the criminal law. Offence data has been classified according to the Australian Standard Offence Classification (cat. no. 1234.0).

• An offence reflects a distinct charge brought against an individual on the basis of relevant Northern Territory legislation. A single incident may involve multiple offences of the same or different types.
• The number of offences processed by the court does not reflect the number of individuals who appear before the court or the number of occasions on which sentence was passed.
• The proportion of actual crime that comes before a court is unknown. Changes in the number of offences processed by the court may not reflect changes in the level of crime in the community.

Principal Penalty - The principal penalty for an offence is the court order that is perceived to be the most severe in relation to each offence. Principal penalties classified as other orders in this section include good behaviour bonds and post-court juvenile diversions.

Quarterly Daily Average - The Quarterly Daily Average is the number of persons held in institutions per day over the stipulated three month period. The quarterly daily averages have been rounded to the closest whole number - as a result discrepancies may occur between the sum of components and the total.

Traffic offences and traffic infringement notices - These figures are not unique counts of traffic offences as one infringement may contain more than one offence. Traffic offence data cannot be reconciled with traffic infringement notice data because this information is recorded on two different systems. Traffic infringement notice data also includes speed camera offences which are not recorded in the traffic offence data.

People Smugglers - are foreign nationals convicted under federal legislation of the transportation of illegal migrants to Australia. The influx of people smugglers started in August 1999 when they represented 4% (or 22 prisoners) of the prison population. By September 2001 they represented 21% (or 144 prisoners) of the NT prison population. Since 2001 the number of people smugglers has declined. People Smugglers are counted as non-Indigenous prisoners.

Protective Custodies - Many factors can influence crime statistics such as changes in the age composition of the population, legislation, police enforcement practices and reporting by the public to the police. Caution should be taken when interpreting these statistics.

Minerals

Other nonmetallic minerals include barite, crushed rock, gravel, limestone, quicklime, vermiculite, soil, sand, dimension stone/sandstone and salt.

Northern Territory Economy

Community Government Council (CGC) - A local government authority constituted under the NT Local Government Act to provide local government services. CGCs have gazetted boundaries and are legally constituted as Local Government Areas.

Incorporated Association (IA) - A body constituted under the NT Incorporations Act with roles and responsibilities similar to local government municipal councils. IAs are funded by both the NT and Australian governments to provide local government services in geographic areas not included in any other Local Government Area. IAs do not have clearly defined boundaries.

Local Government Finance - Local Government Finance data is sourced from state/ territory Local Government Grants Commissions, or equivalent. The ABS quality assures this data primarily at the state/territory level. Clients should be advised that unit record data remains largely as reported by councils to the relevant Grants Commission. This approach can result in the sum of the data released at the unit level differing from published state and territory totals. Further information is available from Government Finance Statistics, Australia, 2005-06 (cat. no. 5512.0).

Baraunga Manyallaluk, Gulin Gulin & Weemol and Wugularr merged in 2004 to form Nyirranggulung Mardrulk Ngadberre Regional Council.

Off-Shore Areas & Migratory

Includes people who are enumerated on offshore oil rigs, drilling platforms and the like, aboard ship in Australian waters, or on an overnight journey by train or bus.

Overseas Arrivals and Departures

Overseas Arrivals and Departures (OAD) data refers to the arrival and departure of Australian residents or overseas visitors, through Australian airports and sea ports, which have recorded incoming or outgoing passenger cards. OAD data describes the 'number of movements of travellers' rather than the 'number of travellers', such that individuals may be counted for multiple movements in a given reference period.

Australian Resident - A person identifying themselves as an 'Australian resident' when completing an Incoming of an Outgoing Passenger Card. This excludes persons travelling on Temporary Entry visa.

Long Term Resident Departure - Departure of a person identified on the Outgoing Passenger Card as an Australian resident who is intending to stay overseas for 12 months or more before returning to Australia.

Long Term Resident Return - Arrival of a person identified on the Incoming Passenger Card as an Australian resident who has been overseas for 12 months or more since their last departure from Australia.

Long Term Visitor Arrival - Arrival of a person who is a visitor or temporary entrant intending to stay in Australia for 12 months or more before their next departure.

Long Term Visitor Departure - Departure of a person who is a visitor or temporary entrant whose stay in Australia was for 12 months or more from their previous arrival.

Short Term Resident Departure - Departure of a person identified on the Outgoing Passenger Card as Australian resident who is intending to stay overseas for less then 12 months before returning to Australia.

Short Term Resident Return - Arrival of a person identified on the Incoming Passenger Card as an Australian resident who has been overseas for less than 12 months since their last departure from Australia.

Short Term Visitor Arrival - Arrival of a person who is a visitor or temporary entrant intending to stay in Australia less than 12 months before their next departure.

Short Term Visitor Departure - Departure of a person who is a visitor or temporary entrant whose stay in Australia was less than 12 months from their previous arrival.

Permanent Departure - Departure of a person identified on the Outgoing Passenger Card as an Australian resident intending to permanently depart from Australia.

Settler Arrival - Arrival of a person intending to settle in Australia.

Settler - A person arriving in Australia who holds one of the following:

• a permanent visa,
• a temporary (provisional) visa where there is a clear intention to settle, e.g.. Intending Marriage visa,
• a New Zealand citizen who indicates an intention to settle,
• a person otherwise eligible to settle, e.g. an overseas-born child of Australian citizens.

Road traffic accidents

A road traffic accident is an unpremeditated event which results in property damage or the death of/injury to a person and is attributable to the movement of a vehicle on a public road (including vehicles entering or leaving a public road).

Fatality - Where a person is killed outright or dies within 30 days of being involved in a motor vehicle accident, and their death was directly attributed to injuries sustained in the accident.

Injury - Where a person sustained some degree of injury as a direct result of a motor vehicle accident. The three levels of injury in the Northern Territory are:

• treated and admitted to hospital;
• treated but not admitted to hospital; and,
• injured but did not seek treatment.

Rates per 1,000 or 10,000 population

Rates are calculated using the 2001 Census of Population and Housing based Estimated Resident Population figure corresponding to the relevant year.

Rounding

Where figures have been rounded, discrepancies may occur between sums of the component items and the totals shown.

Tourism

Tourism NT information is derived from Tourism Research Australia's National Visitor Survey (NVS) and International Visitor Survey (IVS). Data from these surveys can be provided by the SLA level and the tourism region level. However, this publication provides data by tourism areas. Tourism areas are based on the boundaries of Regional Tourism Associations (RTAs) across the Northern Territory. The areas are as defined:

• The Top End Area includes the Darwin, Kakadu and Arnhem tourism regions.
• The Katherine Area includes the Katherine and Daly tourism regions.
• The Barkly Area comprises of the Tablelands tourism region.
• The Centre Area includes the Alice Springs, Petermann and MacDonnell tourism regions.

As the NVS and IVS are subject to sampling variability, annual average data over a three year period is used to increase the amount of responses on which visitor estimates are based, improving reliability. This is particularly necessary when profiling NT tourism regions. Some data within tables are annotated 'not for publication' (np) and are not published as sampling variability is too high for practical purposes.

Tourist Accommodation Survey - Tourist Accommodation Survey (cat. no. 8635.0) The ABS Region definition is as follows:

• Darwin Tourism Region equates to Darwin SD and Environs,
• Katherine Tourism Region equates to Katherine Region,
• Alice Springs Tourism Region equates to the township of Alice Springs only,
• Other includes balance of Central Region (Statistical Local Areas of Petermann, Sandover-Bal and Tanami), Darwin Region Balance, East Arnhem Region and Barkly Region.

Visitor - Tourism Research Australia defines a visitor as someone who has travelled at least 40 kilometres from their usual place of residence and who will spend at least one night away from home. Also, to be included the trip must be short-term. A short-term trip is defined as at least one night but less than 90 nights spent in the NT (Table 13.1).

Visitor expenditure - Estimates of visitor expenditure are based on the amounts visitors say they have spent while in the NT. Thus, the expenditure is a direct expenditure estimate only.

Visitor nights - Estimates of visitor nights take into account the total number of nights people spend in the NT. For example, if a family of four spends 10 nights in the Territory this family represents four visitors and 40 visitor nights.

Vocational Education and Training (VET)

Client figures refer to the number of individuals enrolled in courses or modules with each client being counted only once regardless of the number of courses or modules they may be enrolled in. Course enrolment figures exclude students enrolled in module only activity. Students enrolled in more than one course are counted more than once in course enrolment figures.

Data based on the application of ABS 2004 ASGC concordance (SSD to postcode) may result in totals not adding up between similar categories i.e. clients by sex / clients by Indigenous status and course enrolments by sex / course enrolments by Indigenous status. In editions prior to 2006 of this publication the data was based on the NT Government's postcode apportionment approach and care should be taken when making comparisons between data published this year and before 2006.
