Hi aviadler-ga,
A recent Webinar was held to discuss a software developed in
association with USPS that was capable of keeping track of "movers" in
the United States. At the presentation, the following facts were
presented:
"There are presently 140 million addresses deliverable by the USPS"
"The monthly rate of address deterioration is approximately 1.4%"
"Within just six months, about 8.4% of addresses in a typical mailing
list have the potential to be inaccurate due to move changes."

With the above facts, we can conclude that during a one year period,
there is an upper limit of 16.8% of the US population that changes
their mailing address. The reason this is an "upper limit" and not an
exact figure is due to the fact that the same people may move several
times a year, therefore it is actually a little lower. From
professional experience in this area (dealing with data sets of
millions of US residents), I gauge this value to be closer to 10%.
Hopefully that answered your question :)
Cheers!
