What do all the housing values in a city add up to? For eight American metro areas, the housing values are over $1 trillion:

According to residential real estate website Redfin, less than 10 metro areas in America are now worth $1 trillion in collective real estate home values. Most of those areas make sense for the list, like New York, Boston and Atlanta (the latter of which has a metro population of more than 6 million people). Anaheim, on the other hand, has a population of about 350,000 people, and for years fought to disengage itself from the ignominious nickname “Anacrime,” despite being home to the so-called happiest place on Earth…

The Orange County city reached its recently minted status due to an explosion in the real estate market in that area, with home prices up more than 12% over the past year, Redfin says. To source its findings, the Seattle-based company relied on aggregate home sale data for almost 100 million homes across the U.S.

San Francisco, meanwhile, has not reached trillion-dollar status yet, but that’s only because the city itself is so small. When combined with other large area real estate markets in San Jose and Oakland, the number jumps to a staggering $2.5 trillion. The other cities that did cross the $1 trillion threshold are Chicago, Washington, D.C., and Phoenix.

Nationally, the biggest overall rise in home values comes from more rural and suburban areas, Redfin says. The high cost of homeownership in Anaheim specifically points to ongoing issues in California around housing supply and affordability. Orange County has long been a wealthy area in aggregate, with pockets of affordability. Now, many prospective homeowners may be feeling the squeeze to leave, departing for less expensive homes in places like the Inland Empire and Bakersfield.

To some degree, this measure may not have much value. The biggest metro areas are on this list. (Missing are Dallas and Houston.) Have a lot of people and have relatively high prices and a place ll make this list.

On the other hand, Anaheim does seem like a bit of a surprise. It is a suburb of Los Angeles. In 1950, it had just over 14,500 residents. It grew tremendously in the postwar era. According to the Census Bureau, it has a median housing value of over $713,000.

What other suburbs could be close to joining this list? They would need to be large and expensive. This would rule out many communities in the Northeast and Midwest where suburbs tend to be smaller. Are there some Sunbelt or West Coast suburbs that could join the list soon?
