Hi, I have a question

I am trying to compare changes in the Puerto Rican population in metro areas from 2000 to 2015. Are the 5% ACS 2000 and 1% ACS 2015 datasets comparable?

In other words, if the proportion of PR in let’s say Miami in 2000 was 1.5 and the proportion of PR in Miami in the 1% ACS 2015 is 2.5, can I interpret this a one percent increase? I am concerned about the accuracy of this kind on interpretation because the sample sizes different (5% vs 1%)

I am using the 2013 metroarea variable to account for changes in the boundaries between the two datasets.

Any information would be very helpful.

Cheers,
