STRATANN
Annual stratum for variance estimation

Description

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

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

From 1996-2001, STRATANN were statistically independent from year to year. Beginning in 2002, strata are constant within sample design period. For analysis, researchers need to use STRATANN in conjunction with PSUANN to account for stratification and clustering when computing variance estimates with MEPS data.
