The most obvious difference between the two databases is the sample size of
each. The 18,000-household sample in the MAISY RECS household databases is
designed to provide statistical accuracy at the state and national levels
while the 6.7-million household MAISY sample is designed to provide
statistical accuracy at the ZIP, county, metro, utility service area, state,
and national levels. The larger number of MAISY Database households supports
a greater level of segmentation. MAISY Databases also include 15-minute
loads and a variety of additional variables.
