*The 2011 survey included Unity State, which we exclude here to compare the 2011 and 2015 results.
†The 2011 sample size should have been 66 counties×19 villages=1254 for all eight client populations (see online supplementary table S1), but was reduced for all of the client populations due to missing data.
‡The 2015 sample size should have been 71 counties×19 villages=1349 interviews per client population, but was actually 1348, as the records of one village were missing.
NA, not applicable; SD, Standard Deviation.
