Survey Weights and Data Analysis

Sampling and post-sampling weights are used in the NAWS to adjust the relative value of each interview so that population estimates may be obtained from the sample.

The composite weight variable, PWTYCRD, is included in the NAWSPAD file; it should be used in all analyses to generate unbiased estimates. Additional information on using the weights is available in An Introduction to Analyzing the NAWS Public Access Data.

An example of how to use the WEIGHT command in SAS to obtain the weighted percentages of male and female crop workers in fiscal year 2021-2022 is as follows:

proc freq data=(name of file);
table GENDER;
where 2021 le FY le 2022;
weight PWTYCRD;
run;
