The article €œGoing Wireless€ (AARP Bulletin, June 2009) reported the estimated percentage of households with only wireless phone service ( no landline) for the 50 states and the District of Columbia. In the accompanying data table, each state was also classified into one of three geographical regions€” West ( W), Middle ( M), and East ( E).
