--The most popular housing type? Single-family detached. Almost half the homes in the Baltimore metro area fall into this category.

Nearly 30 percent are single-family attached, such as townhouses and rowhouses.

Fourteen percent of homes are within buildings that have at least 10 units.

--A three-bedroom situation is most common, with 40 percent of homes in that category.

Twenty-four percent have two bedrooms.

Nineteen percent have four bedrooms.

Eleven percent have one bedroom.

Just over 5 percent -- about 60,000 homes -- have five bedrooms or more.

And about 1 percent are studio situations, with no bedrooms at all.

--The typical monthly housing cost for owners with a mortgage is just under $1,800.

For owners without a mortgage, it's about $500.

For renters, it's just under $1,000.

--Household size is a bit larger, on average, for owners.

Owner-occupied units have an average of 2.7 people, compared with 2.3 people in rented units. 

--More than half the metro area's households moved into their current home within the last decade.

A full quarter moved in 2005 or later, so you can see why there might be a fair number of underwater folks out there. Slightly less than a quarter, by contrast, last moved before 1990.

All these statistics come from the American Community Survey's most recent five-year estimates, a look at trends from 2005 through 2009. 

So: Are you typical?
