In johnrbryant/nzreg: Data on New Zealand Regions

Description Usage Format Details Warning Source

The data come from the "address 5 year ago" question in the population census. "region_orig" is the person's region 5 years before the census, and "region_dest" is the person's region at the time of the census. The counts have been rounded to multiples of 3. Counts below 6 are suppressed in the original data, to preserve confidentiality. Values for these counts have been imputed, by fitting a loglinear model to the data, and then randomly drawing 0's and 3's, based on the fitted totals.

1	internal.mig

An array with dimensions "age", "sex", "region_orig", "region_dest", and "time"

age means age at the start of the 5-year interval - not age at the time of the census.

Censuses in New Zealand are generally carried out at 5-year intervals. The 2011 Census was, however, delayed to 2013 because of an earthquake. This means that there is a gap in the series between the periods 2001-2006 and 2008-2013. If using the package dembase, it is necessary to override the defaults for function Counts, which assumes that time dimensions do not have gaps:

mig <- Counts(nzreg::internal.mig, dimtypes = c(time = "state"))

Custom tabulation from Statistics New Zealand.
