subject to interviewer bias. Since there is to be no up-to-date
list of households, simple random sampling is out.  Besides, if
attitudes are to be affected by the distance from the proposed
site, the households should be broken up into strata, with
households of comparable distance in the same strata.  That leaves
as choices "stratified, multistage cluster sampling" and
"stratified random sampling".  But if there is no up-to-date
listing of households for the city, there are none for the
individual strata, either.  So random sampling within each strata
is out, too.  This leaves stratified multistage cluster sampling
as the best of the choices. <p>
