3. Which option for the size of SA1 would best meet your data needs?

T Tania Public Seen by 260

a) Option 1 (0 or 100–200 usual resident population)
b) Option 2 (0or 400– 00 usual resident population)

OPTION 1: 0 or 100–200 usual resident population count

An SA1 of 0 or 100–200 usual residents will allow for the following data to be released without confidentiality suppression.
• All level 1 standard classifications for census variables. This is the 2013 Census information published for meshblock.
• Some classifications for census variables will be available at more detail (level 2) where there are fewer categories, for example birthplace, ethnic groups, religious affiliation, and household composition.
• Some basic multiple variable tables, for example:
o ethnicity by age life cycle groups by sex
o Māori descent by age life cycle groups by sex
o languages spoken by sex.
• All rural centres. The 2013 Census found that rural centres (defined by area unit) contained between 128 and 1325 usual resident population counts. With an SA1 between 100 and 200 dwellings, detailed data will be available for small rural centres. (Note: We are also reviewing the urban/rural geography, and so criteria and boundaries may change.)

The majority of SA1s will have between 100 and 200 usual residents or zero population. In a small number of cases, the maximum threshold of 200 people will be exceeded due to the presence of apartment blocks or retirement villages which are unable to be separated.

OPTION 2: 0 or 400–500 usual resident population count

An SA1 of 0 or 400–500 usual residents will allow for the following data to be released without suppression:
• All level 1 standard classifications for census variables, as was published for the 2013 Census at meshblock level.
• All level 2 classifications for census variables. Level 2 provides more detail than the standard output classification historically used for publishing meshblock data (level 1).
• Some multiple variable tables, for example:
o tables listed in option 1
o ethnicity by age (5 year groups to 65+) by sex
o Māori descent by age (5 year groups to 65+) by sex
o languages spoken by age life cycle groups by sex
o birthplace by age life cycle groups by sex
o birthplace by age (5 year groups to 65+)
o household composition by age (5 year groups to 65+) by sex
o ethnicity by languages spoken
o birthplace by ethnicity by sex.
• Most rural centres. Sixty nine percent of rural centres have usual resident population counts greater than 400 people. Twenty nine of the 133 rural centres (as defined by area unit) had between 400 and 500 usual residents (22%). Option 2 would leave 31 percent of the 2013 rural centres too small for statistical reporting.

As a point of comparison, option 2 is larger than the average 2013 meshblock (0.2 percent of 2013 meshblocks contained 400–500 usual residents) and smaller than most area units, so it will provide more information than has historically been available.

I would like to have Option 2. This option can actually provide more useful information that previously including the multiple variable tables, which people working in DHBs will find meaningful, e.g. for planning, funding and service provision.
