The Census bureau comes out with snapshots of daily life in this country from time to time. Data from the 2011 American Housing Survey -- where we live and how we live -- was released today.

The median year that occupied homes in this country were built, where exactly half are new and exactly half are older, was 1974. A little under half of owner-occupied homes have working carbon monoxide detectors. About three-quarters of Americans who own their homes have central air conditioning.

The median monthly mortgage payment for homeowners -- again, back in 2011 -- was $1,015.
