Private equity firms poured some $443 billion into American companies last year, according to a new survey.
This was a 27% increase over 2012, the Private Equity Growth Capital Council reported in its fourth annual investment study.
The analysis ranks the top 20 states and congressional districts by investment value and number of investments.
"The companies in states across the country that receive private equity investment are able to expand their businesses, develop new innovations and hire workers," Steve Judge, president and chief executive of the PEGCC, said in a statement.
"The data shows that private equity investment cannot be underestimated as a positive economic force in the U.S. that grows businesses and creates jobs."
Earlier this year, the PEGCC reported that although overall private equity had fallen in the first quarter from the previous one, the sector's activity was still "a bright spot for the U.S. economy."
Here are the PEGCC's top 20 states by private capital invested in 2013.
