Figure 5.  Primary Market Areas

U.S. map showing the Primary Market Areas. These indicate:

Primary market areas for cocaine, methamphetamine, heroin, and MDMA were determined through analysis of public health data and law enforcement reporting regarding use in these areas and the extent to which wholesale quantities are distributed from these areas to other markets. Primary market areas for marijuana were determined based on distribution alone.

Formula 1. Nonresponse Adjustment Factor

Graphic showing the formula for calculating the nonresponse adjustment factor for each stratum j.

The nonresponse adjustment factor for each stratum j is equal to the sum of the base weight times the poststratification factor for each of the
responding and nonresponding agencies in stratum j divided by the sum of the base weight times the poststratification factor for only the
responding agencies in stratum j.

Return to Formula 1.

   

Formula 2. Final Weight for Responding Agencies

Graphic showing the formula for calculating the final weight for each responding agency.

The formula is: the final weight is equal to the base weight times the poststratification factor times the nonresponse adjustment factor.
