Which States are Most Similar to California? 2.0

Have you ever wondered how similar or different two states are? The State Similarity Index attempts to quantify how similar states are to each other relative to other states. The index is a statistically-based way to measure this. The index weights equally five major aspects of states: their demographics, culture, politics, infrastructure, and geography. The research combines 1,000 different data points. Each aspect was roughly balanced evenly between quantity/percentage and quality/type. See this post for a full explanation: State Similarity Index

Similar to states along the Pacific Coast

Few states are very similar to California. The top two, Oregon and Washington, are the only other states on the US mainland to border the Pacific Ocean, however these states also have some significant differences with California as well. People in the top five states are generally more liberal and tend to favor Democrats. These states have all legalized marijuana and have few restrictions on abortion. In addition, their people tend to have the same Western accent.

Top 5 States Most Similar to California

  1. Washington is another mountainous state on the Pacific Coast. The states both strongly favor the Democratic Party. Neither state has voted for a Republican president since 1988 or a Republican senator since 2000. They have the two highest minimum wages in the country. California and Washington also have favorable laws to immigrants since they are both sanctuary states and allow undocumented people to get driver’s licenses. One big difference is that Washington has a far lower percentage of Latinos. However both states have a significant number of Chinese, Vietnamese, and Filipino immigrants. Still, Washington is significantly colder than California and has far more rainfall.
  2. Oregon is very similar to Washington. It is another liberal state that strongly favors the Democratic Party. California and Oregon both gained statehood in the 1850s and were part of the Union during the Civil War. Oregon borders California to the north, so the states have similar geography. Both have large areas of temperate coniferous forests, but also have desert areas. They also have about the same percentage of agricultural land, although Oregon grows more wheat. However, like Washington, it has far fewer Latinos.
  3. Nevada borders California to the west. While California is famous for its beautiful beaches, Nevada is landlocked. Still, the states have many similarities. Both were originally part Mexico before they were ceded to the United States. Nevada also has many immigrants from Mexico. Both states have fewer high school graduates than average and a high percentage of unionized workers. However, Nevada’s laws are less favorable to unions. There are also several differences in their gambling and smoking laws, as California’s are more restrictive.
  4. New Mexico does not border California, but these states still have a lot in common. They both have a large Latino population and most have their origins in Mexico. Still, New Mexico has a higher percentage of Native Americans and far fewer Asians than California. Both states tend to vote for Democrats in state-wide elections. However, New Mexico is not as wealthy as California. Both states are mountainous but New Mexico does not have any coastline.
  5. Colorado is more east than the other states on this list. It is significantly colder, but has about the same amount of rainfall and is also very mountainous. Their people have a similar income per capita and a similar percentage of millionaires. In addition, both states favor Democrats and have laws that are friendly to immigrants. Still, Colorado has less restrictive gun laws and does not allow wine or spirits to purchased in the grocery store like California.

Four of five least similar states to California are in the Southeastern portion of the United States. These states tend to be far more conservative than California and favor Republicans.
