California has been growing at a rate slower than other states. When it comes to domestic migration, it exports more people to other states than it accepts.

When it comes to international migration, net migration is less than births minus deaths, and that's with a low birth rate.

In the early 1960s, California had a population of 15 million and built 250k-300k homes per year. Currently California has a population of 40 million and build 80k homes per year.

After the next census, California is expected to lose representation in the House because most other states are growing faster than California.

California has had a major major change in population and building styles since 1980, but policy decisions are still made under the assumption that we are living with the 1960s numbers for building and population.
