Hello. This is my very first post, and I was hoping someone could help me answer a question I've long asked myself. How exactly are rank/size of a market determined? I mean, San Diego is ranked the #17 market with population 2,536,000, according to radio-info, http://radio-info.com/markets/. I see the markets are ordered from largest to smallest, by rank (which, in turn, is also by population). However, the population of San Diego (county, thereby, San Diego area) is just over 3 million. Its been hovering right around 3 million for the last decade, yet for Arbitron purposes and other such things I always see it around 2.5 million. What's happened to the other 500,000 people in the San Diego area?
This, of course, is a question based on mere observation and I dont pretend to know the workings of the industry, I am just basing this off of my own personal knowledge. So can someone please clear this up? Am I not looking at things correctly? Does population get tracked some other way, where half a million people dont count? Does that 2,536,000 mean something else? Please help. This has long stumped me! Thanks
