Arbitron Lacks 2000 Data for Fall Survey

Arbitron said it would base its fall survey on “updated and projected Census 2000 data, updated and projected to Jan. 1, 2002.”
“Because appropriately detailed age/sex data from Census 2000 was not available in time for the updates,” said Thom Mocarsky, Arbitron’s vice president of communications, “estimates for age/sex demographics within the total population will continue to be based on 1990 Census data, updated and projected to Jan. 1, 2001 for the Fall survey.”
In a statement, the company stated that it has partial census data that demonstrates that there will be some market rank changes beginning in fall 2001.
“These are the changes that will be the most important to broadcasters,” Dan Estersohn, senior demographer at Arbitron said.
Late in the fourth quarter, Arbitron will update age/sex demographic estimates for use with the winter and spring 2002 surveys.
The impact of the Fall 2001 population estimates update on individual markets can viewed using the Market-Specific Comparison application, located on the Arbitron Web site at www.Arbitron.com/radio stations/census.htm.
