Larger broadcast service areas correlate with higher salaries, but not as directly as with higher budgets. That’s because you find low budget stations in large markets, and they pay low budget salaries not large market salaries. (Go here for news salaries by news budget size.)
Here are three charts showing the top 10 annual average salaries in public radio news jobs according to the “market size” of the respondents. These market size groupings are based on the population within the broadcast service area of the responding public radio stations. There are more than 100 respondents per each market size sample, but the number of respondents per job title can be quite low depending on the rarity of the title.
