Following a trend that has been ongoing for several years, the share of foreign-born Latino in the United States is at its lowest rate since 2000, based on a new statistical analysis released Monday from the Pew Research Center.

“Today, 34.4% of Latinos are immigrants, down from a peak of 40.1% in 2000,” Pew research assistant Antonio Flores stated. “And the share that is U.S. born has grown to 65.6% in 2015, up from 59.9% in 2000. This decline in the foreign-born share extends across the largest Latino origin groups. The foreign-born share among Guatemalans (61.3% in 2015) fell by 17.2 percentage points during this time, the largest percentage-point decline of the six largest Hispanic origin groups. Salvadorans’ foreign-born share (58.8% in 2015) also had a significant drop, declining 16.9 percentage points. Meanwhile, the Mexican foreign born share (32.2% in 2015), had a smaller decline–9.3 points.”

The new Pew report also said the U.S, Latino population in 2016 is close to 58 million people, “accounting for half of national population growth since 2000,” about 18% of the total U.S. population. Despite the growth, U.S. Latinos are not the fastest-growing racial of ethnic group. Asians had a 3% rate between 2015 and 2016, while Latinos were at 2%. growth 2.0% during the same time period.

“The slowing of Hispanic population growth is occurring,” Flores wrote, “as immigration to the U.S. from Mexico levels off and the fertility rate among Hispanic women declines.”
