New research shows Texas healthcare spending is rising faster the rest for the United States.

The study, published Tuesday by the University of California, San Diego, finds that over the past five years, healthcare spending per capita in Texas has risen by over 20% while the national average has remained stable.

The study found that Texas healthcare expenditures were $6,638 more per capita than the national total.

This means Texas healthcare is now spending more per person per year than the US overall, or nearly $18,000 per person.

While the report does not find a correlation between healthcare spending and income, it does say the state’s healthcare spending has grown more slowly than the overall US healthcare spending over the same period.

“The state has made great strides in expanding access to health care services and improving patient outcomes in recent years, but healthcare spending remains a challenging burden for the state,” the authors wrote.

“Our study highlights a number of ways in which Texas healthcare has grown so rapidly, but also shows the need for the legislature to further invest in healthcare to meet the growing needs of its population.”

In 2015, Texas healthcare cost the state $13,973 per capita.

By 2020, that figure was projected to be $31,000.

The average American household earned $44,200 per year.

More than half of Texas’ population of about 1.3 million is covered by Medicaid, the federal healthcare program for low-income people, according to the study.

The state has seen a significant increase in Medicaid enrollment, though, from less than 5,000 people in 2014 to over 30,000 in 2020.
