For the majority of geographic areas, especially those expected to be
undergoing continual population growth or other demographic changes at a
relatively steady rate, it may be better to perform a linear regression
on the annual ACS data with respect to year, then interpolate or
extrapolate to the year of interest, than to average the annual ACS
data. Obviously there are other areas that have experienced significant
discontinuities in population or demographic characteristics for which
this method would not be very reliable, but then neither would using
multi-year ACS averages.
