This collection focuses on how changes in the legal drinking
age affect the number of fatal motor vehicle accidents and crime rates.
The principal investigators identified three areas of study.
First, they looked at blood alcohol content of drivers involved in
fatal accidents in relation to changes in the drinking age. Second,
they looked at how arrest rates correlated with changes in the drinking
age. Finally, they looked at the relationship between blood alcohol
content and arrest rates. In this context, the investigators used the
percentage of drivers killed in fatal automobile accidents who had
positive blood alcohol content as an indicator of drinking in the
population. Arrests were used as a measure of crime, and arrest rates
per capita were used to create comparability across states and over
time. Arrests for certain crimes as a proportion of all arrests were
used for other analyses to compensate for trends that affect the
probability of arrests in general. This collection contains three
parts. Variables in the Federal Bureau of Investigation Crime Data file
(Part 1) include the state and year to which the data apply, the type of
crime, and the sex and age category of those arrested for crimes. A
single arrest is the unit of analysis for this file. Information in
the Population Data file (Part 2) includes population counts for the
number of individuals within each of seven age categories, as well as
the number in the total population. There is also a figure for the number
of individuals covered by the reporting police agencies from which data
were gathered. The individual is the unit of analysis. The Fatal Accident
Data file (Part 3) includes six variables: the FIPS code for the state,
year of accident, and the sex, age group, and blood alcohol content of
the individual killed. The final variable in each record is a count of
the number of drivers killed in fatal motor vehicle accidents for that
state and year who fit into the given sex, age, and blood alcohol content
grouping. A driver killed in a fatal accident is the unit of analysis.

States that raised the drinking age between 1981 and 1986
were eligible for inclusion in the study test group. Additionally, the
year of change and the years in which more than 20 percent of the drivers
in the relevant age categories were affected by a "grandfather"
clause were excluded. Also, only states and years in which at least 60
percent of the killed drivers were tested for blood alcohol content
were included. States that had not changed their drinking age between
1980 and 1987 were eligible for inclusion in the control group.

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:
Checked for undocumented or out-of-range codes.

- 2006-03-30 File CB9685.ALL.PDF was removed from any previous datasets and flagged as a study-level file, so that it will accompany all downloads.
- 2005-11-04 On 2005-03-14 new files were added to one
or more datasets. These files included additional setup files as well
as one or more of the following: SAS program, SAS transport, SPSS portable,
and Stata system files. The metadata record was revised 2005-11-04 to
reflect these additions.
- 2001-11-16 The data files were reformatted to logical record
length format, and a corresponding codebook and SAS and SPSS data
definition statements were created. Existing hardcopy documentation
was converted to PDF.
