Comparing ZCTA poverty rates, 5 year estimates

Hi!  I usually run trend analysis on poverty rates between two two 5-year periods for all the ZCTAs in my county (currently 08-13, and 14-18).  I am considering testing recent poverty rate estimates for all ZCTAs in my county against the overall poverty rate for the county to highlight ZCTAs with significantly higher/lower rates than the county overall.  I am not a stats expert and wondering if anyone here could point out any statistical reason I shouldn't do it this way.  Thanks! 

  • Hello,
    Statistically this is fine as long as you use 5-year data for the county-level poverty rate so that you are comparing apples to apples.
