Disregarding the houses, the most popular form of apartment building in the US right now is called a "5 over 1" which has a wood frame on top of a concrete first floor. The facades often aren't wood, but the buildings themselves are usually wood. Most "brick" houses in the US have a brick facade over a wooden house.
The few exceptions are in the densest cities in the US, like New York, where new construction is concrete and steel.
Canada, I am sure, is the same. Mexico and South America, not so sure. I have been around some places in Central America that have tons of wood construction, and so did the parts of Argentina and Brazil I have seen, but you may have better information. Many houses that you think are concrete or brick actually have a wood frame.
