Wondering if it is statistically valid to average data from two or more 1-year supplementals. If so, can I also average the MOE or would I use another approach to find the combined MOE?
Purpose: I'm doing data visualizations of socioeconomic changes over time in a 5-county area, and each of the counties are 20-30K population.
I'd like to use data from five periods:
2000 Census
2005-2007 3YR
2008-2010 3YR
2011-2013 3YR
And ... since the 3YR was discontinued... in October when the 2016 supplemental is released, I'd like to combine the 1 YR supplementals for 2014-2016 to make a 3YR for that period.
Thanks for any feedback on this.
I think David Hubble gave a presentation on this at the recent ACS Data Users conference. A PDF and video can be found at https://acsdatacommunity.prb.org/p/2017_acs_conference
