Behind El Paso and Salt Lake City — which seems weird to me, but what do I know. Scarborough Research explains why these cities rank the highest:
[Texters] are 49 percent more likely than all cellular subscribers to be ages 18-24, 14 percent more likely to be Hispanic, and 24 percent more likely to be African-American. Scarborough points to these similarities as likely reasons why El Paso, Salt Lake City, Dallas and Memphis are the top text messaging markets. El Paso andDallas both have Hispanic compositions that are well above average. Further, Salt Lake City and El Paso are top markets for 18-24 year old adults, and Memphis is a leading city for African-Americans.
So there.
