BOULDER - Mobile-app developers have created more than 8,000 jobs in Colorado and have a $429 million economic impact, according to a report released Thursday by CTIA-The Wireless Association and the Application Developers Alliance.

The report, commissioned by the industry association of wireless providers and mobile-app developers, compiled data on the number of app developers and other information technology workers companies hire to support their apps. The tally includes people who work for app developers in non-IT jobs, such as marketing and "spillover" jobs created outside the industry.

The report's author, South Mountain Economics LLC, estimates there are 519,000 "App Economy" jobs throughout the United States by that measure. It did not calculate a dollar figure for economic impact.

Colorado ranks 15th when the economic impact of the app industry is compared with other states. California is the state where the industry has the biggest impact, generating about $8.2 billion and accounting for 151,900 employees, according to the report.

The report also tried to measure the relative importance of the "app economy" to each state's total economy. It ranked Colorado 10th in "app intensity," finding that nearly 1 percent of the state's workforce was impacted directly or indirectly by the app industry.

The report is available online at the Application Developers Alliance website,  http://appdevelopersalliance.org, or  http://appdevelopersalliance.org/files/pages/The%20Geography%20of%20the%20App%20Economy.pdf.
