2023 Urban Accessibility Indicator update

For the 2023 IUA, there have been minor updates to align with changes to the urban rural (UR) boundaries and SA1 composition. The drive time analysis has not been re-run since the release of IUA 2018. The Wānaka urban area, whose population has grown to bemore than 10,000 based on population estimates, has been reclassified to a medium urban area in the 2023 UR. However, it will continue to be classified as a small urban area in the IUA until the analysis is re-run for the next major update.

Description

This dataset is the definitive version of the Urban Accessibility Indicator boundaries as at 1 January 2023, as defined by Stats NZ.

The Urban Accessibility Indicator (IUA) classificationprovides a consistent measure of urban accessibility in order to distinguish the degrees of rurality in New Zealand. IUA classifies the geographic accessibility of rural statistical area 1s (SA1s) and small urban areas according to their proximity, or degree of remoteness, to larger urban areas.

The IUA methodology uses drive time from an SA1 address weighted centroid to the outside boundary of the nearest major, large, and medium urban area (from the UR classification), to classify rural SA1s and small urban areas to one of five categories of accessibility or remoteness. Small urban areas and rural settlements are assigned to a single category based on the classification of the majority of their SA1s. The Open Source Routing Machine service using the OpenStreetMap road network was used to calculate the drive times.

Rural SA1s and small urban areas are classified to the following categories:

High urban accessibility:

0 to 15 minutes from major urban areas,

Medium urban accessibility:

15 to 25 minutes from major urban areas,

0 to 25 minutes from large urban areas,

0 to 15 minutes from medium urban areas,

Low urban accessibility:

25 to 60 minutes from major or large urban areas,

15 to 60 minutes from medium urban areas,

Remote:

60 to 120 minutes from major, large or medium urban areas,

Very remote:

more than 120 minutes from major, large or medium urban areas.

The urban accessibility indicator (IUA) classifies urban, rural, and water areas by type. The high and medium urban accessibility categories are considered to be peri-urban.

The indicators, with their codes in brackets, are:

urban areas – major urban area (111), large urban area (112), medium urban area (113),

small urban and rural areas – high urban accessibility (221), medium urban accessibility (222), low urban accessibility (223), remote (224), very remote (225),

water areas – inland water (331), inlet (332), oceanic (333).

A concordance between SA1 and Urban Accessibility can be found on Ariā.

Urban accessibility indicator is also available as an attribute on Statistical Area 1 Higher Geographies 2023 (generalised).

For more information refer to Urban accessibility – methodology and classification or the Statistical standard for geographic areas 2023.

The urban accessibility (UA) classification measures the degree of urban influence New Zealand’s urban areas have on surrounding rural areas. It classifies the geographic accessibility of rural statistical area 1s (SA1s) and small urban areas according to their proximity, or degree of remoteness, to larger urban areas. This classification provides increased understanding of the heterogeneity of rural areas and small urban areas and will allow more extensive analysis and reporting. Understanding the degree of urban accessibility or remoteness is important as it has a major influence on the employment sector, accessibility to services, and population composition and change.

The methodology uses drive time from an SA1 address weighted centroid to the outside boundary of the nearest major, large, and medium urban area (from Stats NZ urban rural (UR) classification) to classify rural SA1s and small urban areas to one of five categories of accessibility or remoteness. The Open Source Routing Machine service using the OpenStreetMap road network is used to calculate the drive times.

A concordance between SA1 and Urban Accessibility can be found on Aria.

Urban accessibility indicator is also available as an attribute on Statistical Area 1 Higher Geographies 2022 (generalised).

Rural SA1s and small urban areas are classified to the following categories:

·High urban accessibility:
0 to15 minutes from major urban areas

·Medium urban accessibility:
15 to 25 minutes from major urban areas
0 to 25 minutes from large urban areas
0 to 15 minutes from medium urban areas

·Low urban accessibility:
25 to 60 minutes from major or large urban areas
15 to 60 minutes from medium urban areas

·Remote:
60 to 120 minutes from major, large or medium urban areas

·Very remote:
more than 120 minutes from major, large or medium urban areas

For more information refer to: Urban accessibility - methodology and classification.

The full classification is shown below:

111 Major urban area

112 Large urban area

113 Medium urban area

221 High urban accessibility

222 Medium urban accessibility

223 Low urban accessibility

224 Remote

225 Very remote

331 Inland water

332 Inlet

333 Oceanic

Areas of 221 High urban accessibility and 222 Medium urban accessibility may be regarded as peri-urban in nature and combined with urban areas for analytical purposes.
