People identifying as Hispanic or Latino are the largest ethnic or racial group in Galt, according to the 2020 U.S. census results.

The census counted the Hispanic population at 11,588, or about 46% of the total population. That is a close-to-15% increase over the 2010 census.

Non-Hispanic whites make up the next-largest group, numbering 10,922 people, or 43% of the population. The white population has decreased over the past decade, both in absolute terms and in share of the population. In 2010, 11,513 white people lived in the city, accounting for nearly 49% of the population.

While they remain a relatively small group, those identifying as multiracial have become the third-largest group in the city, growing from 665 people to 1,218. They now make up nearly 5% of the population.

As a whole, the city has grown about 7% between censuses. The 2010 count recorded 23,647 people living in Galt; in 2020, that number has risen to 25,383.

By the Census Bureau’s measurements, Galt’s level of diversity has risen slightly. The bureau has developed various methods of describing how diverse a locality is, including the “Diversity Index” (DI), which is the probability that two people randomly selected from the population will belong to different ethnic or racial groups. For example, a population evenly split between two groups would have a DI of 50%.

Following the Census Bureau’s methodology, Galt’s DI in 2010 was about 58%. The city’s 2020 DI is 60%. By comparison, in 2020, Sacramento County has a DI of 73%; for California, the figure is close to 70%.

Besides the Latino population, other groups have seen increases since 2010.

The number of people identifying as Asian grew from 745 to 921, approaching 4% of the population. The Black population went from 367 to 442, roughly 2% of the city.

Each of the remaining census-defined groups makes up less than 1% of Galt’s population. The city has 143 American Indian or Alaska Native residents, 72 Pacific Islander residents and 77 people who identify as a race besides those defined by the Census Bureau.
