Unionization rates by Commuting Zone in the United States

This is a computation of predicted unionization rates by 1990 Commuting Zones in the United States. The predictions are for the year 2000.<br><br> Issue: union status is available in the Current Population Survey (Outgoing Rotation Groups), but the CPS does not have county identifiers for the whole population, which are necessary to assign the CZ a CPS respondent lives in. Moreover, even with access to restricted CPS data files, the CPS is meant to be representative at the state level, so estimates at the CZ level may not be accurate. <br><br> Solution: use the CPS Merged Outgoing Rotation Groups (CPS MORG) from 2000 to estimate the probability of being unionized by state, sex, age group and 3-digit industry. Then, use the Quarterly Workforce Indicators (QWI) to get employment figures by county, sex, age group and 3-digit industry. Impute the estimated probability from the CPS MORG at the state, sex, age group and 3-digit industry. Assign each county to its CZ. Then compute weighted average of probability of being unionized by CZ, where employment counts are used as weights. <br>
