The study says the new Californians will be staying in California, which has many implications.
They are more likely to invest in California's future, which means they will be supporting schools and universities. They will be more willing to tax themselves for public services.
The study says the trend is consistent for all racial and ethnic groups.
The percentage of Latinos and Asian Americans is growing. The study says they have a greater desire to stay close to relatives and their communities. The groups are also expected to assume more leadership roles.
In the long-term, this will impact California's economy, especially the housing market. All the young people who stick around will be buying homes vacated by the baby boomers.
The study comes as the public gets ready for the 2010 Census. Workers are already canvassing neighborhoods in the Southland, but the actual population count won't begin until next year.
However, the workers need to identify 145 million addresses, using GPS technology.
Los Angeles city officials stressed the importance of getting an accurate population account. Officials said because they were undercounted, the city lost $184 million.
