This pilot study was conducted to expand the scope of information collected about this forensic science discipline and to help inform future data collections.
The CPFFCL population frame and questionnaire were developed by BJS and the Urban Institute with input from the American Society
of Crime Laboratory Directors and researchers and practitioners in the forensic science field. In April 2015, the Urban Institute initiated
the data collection on behalf of BJS through a web-based data collection interface and mailed questionnaire. Follow-up emails and
phone calls were made to nonrespondents and labs that submitted incomplete questionnaires.
The CPFFCL-14 questionnaire was sent to 409 state, federal, and local publicly funded forensic crime labs that met the project definition of a crime lab.
As part of a separate pilot study, the CPFFCL-14 questionnaire was also sent to an additional 61 state and federal labs that solely analyzed digital evidence and were not among the 409 crime labs in the 2014 CPFFCL.
This data set includes the responses received from the 61 state and federal digital evidence labs in the pilot study. It also includes the responses received from 26 separate state and federal labs that were (1) among the 409 crime labs that met the traditional CPFFCL definition of a crime lab because they were part of a multi-disciplinary lab that also included natural science disciplines (e.g., biology or
chemistry) and (2) reported analyzing digital evidence during 2014.

The CPFFCL-14 questionnaire was sent to 409 state, federal, and local publicly funded forensic crime labs that met the project definition of a crime lab. Of the 409 eligible crime labs that received the questionnaire, 360 (88 percent) provided responses to at least some of the items.
