Where do the statistics come from?
Data for this campaign was pulled from the economic analysis software IMPLAN (IMPLAN Professional 2.0.1018) using 2000 data for the Des Moines Metropolitan Statistical Area. $7,238,520,000 is the total amount of goods and services purchased from out of area vendors annually. We would like to thank Iowa State University economist David Swenson for his assistance in acquiring and interpreting this information.
Input-output models are widely used in economics to study the structure of an economy. They quantify the flow of dollars to and from industries, households, governments and other final demand. A popular input-output model is IMPLAN (IMpact Analysis for PLANning). All data and analysis in this report is based on IMPLAN, unless otherwise noted.
Tulsa-MSA industries, in purchasing intermediate goods and services for the production of their goods and services, purchase 35.9 percent of their needs outside the Tulsa MSA. The lost-dollars total is *$10.6 billion of a $29.5 billion economy. By the numbers: $10.6 billion leaves the Tulsa area economy each year $29 million leaves our economy each day $1.4 million each day could be retained if 5% is returned to our economy *This estimate excludes the labor portion of inputs.
Because unemployment insurance records relate only to persons who have applied for such benefits, and because it is impractical to actually count every unemployed person each month, the Government conducts a monthly sample survey called the Current Population Survey (CPS) to measure the extent of unemployment in the country. The CPS has been conducted in the United States every month since 1940 when it began as a Work Projects Administration program. It has been expanded and modified several times since then.
