I'm trying to find the non-compliance rate for this. So far this is what I found....
" The ACS collects the data using three modes of data
collection, mail, telephone and personal visit. The data is
collected for each monthly sample over a three month time
span. The mail mode uses a pre-notice letter, the ACS
questionnaire and a reminder post card. For those who do
not mail their form back in about three weeks, a
replacement questionnaire is mailed. For all mail returns,
a computer edit checks the completeness of the
questionnaire and if it is incomplete, a telephone follow up
is conducted to try to complete the missing information.
Currently we are getting about a 50% mail response........
"If the questionnaire is not received by the end of the first
month, all cases that have a telephone number (obtained
from a private vendor matching on the mailing address) are
sent to our telephone centers.
About 40% of the cases that
do not mail their forms back have telephone numbers and
a telephone interviews are attempted for these cases. Mail
returns continue to arrive in the mail as the telephone
interviewing is occurring. Telephone interviewing occurs
for a little less than a month.".....
"Finally all cases that have not mailed a form back or
obtained an interview from the telephone call are eligible
for personal visit interviewing. Because of the large
expense of conducting a personal visit interview, only
1 in
3 cases are sent to personal visit interviewing. The personal
visit interviewing starts at the beginning of the third month
and continues to the end of the month."....
"Typically we have seen about a 50% mail response rate
and another 10% telephone interviews. Large cities
generally have a smaller mail response rate, down around
40% while some other areas have mail response rates over
60%. The remaining 40% is subsampled with about 13%
being eligible for personal visit interviewing."
"The cutoff dates to define the hard-to-interview for each
mode were: mail cases are the 17th of the month after mail
out (so for January mail out, all late mail cases were those
received after February 17th), telephone cases are the 25th
of the month of interviewing, and personal visit cases are
the 27th of the month of interviewing."
From what I have gathered trespassing laws do not apply to federal employees so shutting the drive gates does no good, they can enter anyway........I'll see what happens next.....
