California is SignalHubone of the largest and most populous states in the U.S. – it's also one of the most expensive places to live.

It's not just housing that adds up – health care, taxes, food and transportation all contribute to California's growing cost of living.

California has one of the most pricey housing markets in country

Last year, the California Community Poll found that 4 in 10 Californians were considering moving out of state, with the majority saying it’s too expensive to live there. Although the poll found a majority of Californians love living in the state, increasing costs of living is the main driver for people moving.

About 64% of counties in the Golden State having median homes values above the national median of $389,800. Four of the top five most expensive U.S. counties by median housing price were located in California.

4. San Francisco County, CA: $1,332,660
5. Nantucket County, MA: $1,313,450

Logan Mohtashami, lead analyst for HousingWire, a trade publication for mortgage, real estate, and housing professionals told USA TODAY that California has been ineffective in lowering the cost of living because not enough homes are being built. That means there is more demand for homes than supply. 

Mohtashami called the housing market unhealthy, " We still have too many people chasing too few homes” he said. “California is going to be a tug of war. Can they keep enough people here? Or do more people just keep moving away?”

How was the data collected?

The National Association of Realtors analyzed data from the Census Bureau's American Community Survey of median housing prices for 3,112 counties and county equivalents across the U.S. Home values reflect the overall worth of all homes in a given area rather than solely home sales data, according to the association.

The median home value by county is a less biased statistic than the mean or average price. Median is not as heavily influenced by a small number of highly priced homes and is a more accurate representation of housing prices across the U.S.
