2008-2010 National Survey on Drug Use and Health:
Overview and Summary of Substate Region Estimation Methodology

Variance v of the natural logarithm of Theta sub n hat is equal to the square of quantity q. Quantity q is the difference between capital U sub n and capital L sub n divided by 2 times 1.96.
Return to equation 1.

Variance v of the natural logarithm of Theta sub b hat is equal to the square of quantity q1 times the square of quantity q2. Quantity q1 is the difference between upper sub b and lower sub b divided by 2 times 1.96. Quantity q2 is the reciprocal of p sub b multiplied by 1 minus p sub b.

Figure 1 is a U.S. map showing alcohol use in the past month among persons aged 18 or older, by State: percentages, annual averages based on 2012 BRFSS. States listed here in alphabetical order within each group were divided into five groups based on the magnitude of their percentages. States in the highest group (60.7 to 65.4 percent) were Colorado, Connecticut, District of Columbia, Massachusetts, Minnesota, Nebraska, New Hampshire, Rhode Island, Vermont, and Wisconsin. States in the next highest group (56.5 to 60.6 percent) were Alaska, Illinois, Maine, Maryland, Montana, New Jersey, North Dakota, Oregon, South Dakota, and Washington. States in the midgroup (53.1 to 56.4 percent) were Arizona, California, Delaware, Florida, Iowa, Michigan, Nevada, New York, Ohio, Pennsylvania, and Wyoming. States in the next lowest group (47.0 to 53.0 percent) were Georgia, Hawaii, Idaho, Indiana, Kansas, Louisiana, Missouri, South Carolina, Texas, and Virginia. States in the lowest group (29.0 to 46.9 percent) were Alabama, Arkansas, Kentucky, Mississippi, New Mexico, North Carolina, Oklahoma, Tennessee, Utah, and West Virginia.
