The LRA also provides the ranking of local radio listening impressions per week in three key demos: 12+, 25-54 and 35-64. The minimum sample per market is 250 randomly selected and demographically balanced local radio listeners (with no weighting). Only local radio stations are measured (excluding out of market stations or non-radio audio). The LRA is simple to use (in a PDF format), with no software or downloads required. Fees are typically less than $10,000. Discounting available for multiple stations or markets.
