America’s FCC reports the total number of licensed radio stations has risen to 13,977, the highest number ever and nearly 1,200 above the number of licensed stations a decade ago.

The current total includes 6,309 commercial FMs and 4,776 AM stations. Not part of the count is the 831 licensed low-power FMs.

Radio reaches 78% of the total U.S. population, and does even better among key advertiser demographic groups. Arbitron reports that 95% of adults age 18-49 with a college degree and an annual household income of $50,000 or above, tune into radio over the course of a week.
