How to use the EPI extracts¶
1. Download the data¶
Version 1.0.9 of the EPI CPS extracts is available to download here.
2. Unzip and move the files¶
The zip file you downloaded is a collection of Stata data files, one file for each year (or monthly files when annual data is not available). You should decompress those files and move them into an appropriate directory on your computer.
3. Use the data with your favorite statistical package¶
Feel free to just use the datasets just as you would any Stata dataset:
use "/data/cps/epi_cpsorg_2019.dta", clear
/data/cps/with the directory containing the decompressed files.
Alternatively, the Stata command
load_epiextracts is an easy way to load a selection of years and variables of the EPI CPS extracts into memory. First, install the Stata package with
net install load_epiextracts, from("https://microdata.epi.org/stata")
* Load all of the 2016-2017 EPI CPS Basic monthly extracts load_epiextracts, begin(2016m1) end(2017m12) sample(basic) sourcedir("/data/cps") * Load certain variables from the 1990m7-2018m6 EPI CPS ORG load_epiextracts, begin(1990m7) end(2018m6) keep(age lfstat union) sample(org) sourcedir("/data/cps")
help load_epiextractsfor more details.
The haven package will load Stata datasets:
mydata <- haven::read_dta("/data/cps/epi_cpsorg_2019.dta")
4. Cite the data¶
If you use the EPI extracts for your research, please cite the data in your references:
