California’s unique housing demands don’t always match up with the income of its residents. Income inequality is catching up with the economy, specifically the housing market.

California’s household demographics

The fuel for California’s housing market is new housing formation, reliant not just on population growth, but on that population’s access to quality jobs and sufficient income.

Here’s today’s typical California household makeup:

The chart on the left shows the share of California households according to size. The chart on the right breaks this down further to show the characteristics of the head(s) of the households.

Nearly one in two households in California are headed by married couples. Roughly one in four consist of a single person living alone. The rest are made up of those living with non-relatives (roommates or cohabiters) and individuals heading family households with no spouse present (single parents, adult children taking care of elderly parents, etc.).

These percentages are largely unchanged since last decade, despite the brief jump in household size following the Great Recession when family members consolidated households to save money.

The average U.S. household looks significantly different:

  • 60% of U.S. households consist of married couples, well above the 49.5% in California; and
  • 17% of U.S. households are single-person households, well below the 24% in California.

California’s unique housing needs

The Golden State’s tendency toward single-person households ultimately translates to a need for more housing units per individual here in California. Further, these housing units look different than the housing units of most married couples, as single-person households generally:

  • make less money than married households; and
  • desire less space than married couples.

The average single-person living alone earns 34% of what married couples living together make. And that’s not just because in many married households both couples work — households consisting of non-relatives living together (that are just as likely to feature multiple workers) earn 47% of what the average married couple household makes. This suggests that married individuals trend toward higher earnings, one reason being the tendency to wait until financial stability before marrying.

Therefore, while California has a need for more housing due to the greater number of single-person households, these “extra” housing units are more likely to be less costly multi-family dwellings, including condominiums and rental apartments.

Further, this dynamic is only expected to increase through the next few years — peaking around 2024-2024 — as the young generation of would-be first-time homebuyers (Generation Y, and increasingly members of Generation Z) has been forced to put off homeownership due to a delayed entry into the workforce in the aftermath of the Great Recession.

These young adults born in the 1980s and 1990s are often found in urban centers, living with roommates, renting rather than owning. The average homeownership rate for Californians 34 years and younger is only 20%-40%, depending on specific age. Before the Great Recession, the homeownership rate for this age group was five to ten percentage points higher.

Today’s depressing homeownership rate amongst young people translates to a lot of lost home sale transactions. Real estate agents wait anxiously while Gen Y slowly accumulates the savings and income needed to realize their full potential for homeownership.

Smaller paychecks, smaller houses

It’s easy to wave away Gen Y’s and Gen Z’s plight as a young person’s problem, or a blip in an otherwise healthy labor force here in California. In truth, average incomes have been falling behind in California since long before Gen Y came of age, stagnating household formations and in turn weighing down home sales volume.

Accounting for inflation, California’s gross domestic product (GDP) increased by 108% from 1997-2019, at $2.8 trillion in 2019. During the same time, average per capita income in California rose 50%. In other words, GDP has grown at a rate over twice that of income.

GDP is the measure of a state’s total economic output, and a general indicator of broad financial health. However, it clearly doesn’t translate directly to income growth.

A very small amount of the difference can be accounted for things like indirect business taxes and bad debts. But the bulk of the difference is due simply to a few individuals profiting disproportionately to most earners — a situation known as income inequality.

Income inequality: bad for the economy, bad for housing

Here in California, the average income of the top 1% of earners is 31 times greater than the average income of all other earners, one of the largest gaps in the nation, according to the Economic Policy Institute.


Income inequality is not only bad for most income earners; it’s also bad for the economy. In fact, without today’s high level of income inequality in California and the U.S., GDP would actually be significantly higher, according to an Organization for Economic Cooperation and Development study on the link between GDP and income inequality.

Another way to weigh the effect of income inequality on the housing market is to consider the housing demands of 99% of California’s workers against the top 1%. Sure, the top 1% of earners will buy more expensive homes, and often buy a vacation home or two on top of their primary residence. They may even become property investors, buying dozens of properties.

But that is not even a drop in the bucket compared to the housing needs of the 99-percent-ers, which today equals roughly 17.4 million working individuals in California. When profits are distributed just a little more evenly, the purchasing power of the bottom 99% rises. This causes a considerably positive effect on the housing market, as workers can qualify for higher mortgages or rents, and household formation increases as individuals finally gain the income needed to move out on their own.

Share the wealth

Policy changes affecting income inequality usually take the form of changes to the tax code. However, these wealth taxes can be unpopular — despite the truth that:

  • the vast majority of households are well out of danger of ever being subject to such wealth taxes; and
  • the super wealthy are no more worthy of protection from taxes than regular taxpayers, though this is currently the case.

Don’t misunderstand. The top 1% of income earners are neither “bad” people nor purposefully keeping profits out of the hands of employees. But there’s no denying our tax code is set up to favor the wealthy.

For regular income earners, it’s mandatory to give 10%-28% of annual income to the federal government in income taxes each year, on top of sales and state taxes. For the top income earners, the tax rate is 39.6%. However, due to several tax loopholes designed to favor the wealthiest taxpayers, the paid rate ends up much lower.

Some changes that can level the playing field between the super rich and regular income earners are:

  • raising the limit on one of the biggest tax loopholes — capital gains — which is currently set at just 20% for the highest income earning tax bracket (an easy argument to make, since there is no study able to prove the correlation between lower capital gains and economic growth);
  • revising California’s Proposition 13 (Prop 13), which places a disproportionate tax burden on new homeowners;
  • revising rules covering 1031 transactions, which allow real estate investors to put off incurring any capital gains tax on a sale, provided they re-invest appropriately; and
  • adjusting the mortgage interest deduction (MID), which overwhelmingly benefits top income earners, and perhaps instead focusing on deductions for those trying to save up to become homeowners.

Do this, and you’ll see more hard workers making it into the middle- and upper-class. You’ll also see a higher, self-sustainable homeownership rate. California’s homeownership rate is consistently ranked near the bottom of the nation, at 55% going into 2021.

Uphold the status quo, and you’ll continue to see the rift widen between the top income earners and average earners. GDP growth won’t realize its full potential, large corporations will flourish and small businesses will struggle. And in return, the rich will get richer.
