Baseline (Year): 
0.39 (2008)
Target: 
0.38
Target-Setting Method: 
Maintain consistency with national programs, regulations, policies, and laws.
Numerator: 

Number of alcohol related motor vehicle crash deaths reported in FARS

Denominator: 

Total vehicle miles traveled

Comparable Healthy People 2010 Objective: 
Adapted from HP2010 objective
Data Collection Frequency: 
Annual
Methodology Notes: 

    The Federal Highway Administration estimates total vehicle miles traveled using an algorithm that includes gas sales, vehicle registration, vehicle fuel economy data, and other data from the Highway Performance Monitoring System. The National Highway Traffic Safety Administration (NHTSA) defines a fatal crash as alcohol related if either a driver or a nonmotorist has a measurable or estimated blood alcohol concentration (BAC) of 0.08 g/dL or above. BAC is measured as a percentage by weight of alcohol in the blood (expressed as grams per deciliter). An elevated BAC level (0.08g/dL and higher) indicates that enough alcohol was consumed by the person tested to impair normal functions. Only deaths that occur within 30 days of the motor vehicle crash are included (less than 2 percent of the total number of deaths occur after 30 days). FARS data are obtained solely from a State's existing documents, including police crash reports, death certificates (coded to ICD-10 V30-V39 [.4-.9], V40-V49 [.4-.9], V50-V59 [.4-.9], V60-V69 [.4-.9], V70-V79 [.4-.9], V81.1, V82.1, V83-V86 [.0-.3], V20-V28 [.3-.9]. V29 [.4-.9], V12-V14 [.3-.9], V19 [.4-.6], V02-V04 [.1, .9], V09.2, V80 [.3-.5], V87 [.0-.8], V89.2), vehicle registration files, and hospital medical reports.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2014, the baseline was revised from .40 to .38. When the baselines were established the we asked for data rounded to one decimal place. At some later point the guidance changed and we now display rates less that 1.0 with two digits after the decimal place. So the baseline and updates were revised slightly.
