PSUANN
Annual primary sampling unit (PSU) for variance estimation

Description

[ PRELIMINARY VARIABLE: Variable description may change once we confirm the universe and assess the comparability of this variable over time. ]

PSUANN is the annual primary sampling unit variable that represents the impact of sample design clustering on the estimates of variance and standard errors. It is appropriate to use PSUANN to generate annual estimates for all years. For pooled analyses including years before 2002, analysts should instead use the pooled primary sampling unit variable, PSUPLD. For analyses limited to years 2002 and later, PSUANN is suitable for use in annual and pooled analyses.

PSUANN is constant within a sample design period and changes between sample design periods. For analysis, researchers need to use PSUANN in conjunction with STRATANN to account for stratification and clustering when computing variance estimates with IPUMS MEPS data.

Codes
