I am working on a project for the Dept. of Edu that describes English Learners (ELs) in the U.S. using 2011-13 ACS data. I have a strong preference to use the IPUMS data over the PUMS data, but the 2011-13 IPUMS data are not available yet. I have two quick questions to help me choose which data set to use:
Does anyone know when the 2011-13 IPUMS data will be released? Can you say whether it will be released by 2/1/15?
Another researcher suggested combining the 2011, 2012, and 2013 individual year samples. The researcher said the main adjustments I would need to make are dividing the sample weights by 3, and adjusting the dollar variables to constant dollars.
Is adjusting the sample weights for the three year sample as easy as dividing the weights by 3?
The project involves calculating a series of population averages (for ex., the % of ELs by state, the % of ELs enrolled in college, the % of ELs who are single parents).Would these population averages be bias if I divided the sample weights for each year by 3 and stacked the samples into one data set?
