Socioeconomic status (SES) is based on a small area‐level measure of household deprivation derived from the national census (NZ Dep 2018), an ordinal scale of 1–10 where 1 indicates the individual living in a household with the least socioeconomic deprivation. We used the ordinal scale ranging from one to five (quintile), where one represented the areas with the least deprived scores and five with the most deprived scores.
CI, confidence interval.
