Expand All

PHI-13.4 Increase the proportion of local public health agencies that provide or assure comprehensive epidemiology services to support essential public health services

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Profile of Local Health Departments
Changed Since the Healthy People 2020 Launch: 
Baseline (Year): 
35 (2008)
Target-Setting Method: 
Total coverage
Target-Setting Method Justification: 
Comprehensive epidemiology services are fundamental to public health infrastructure. The target is based on an increased number of Public Health Training Centers, more activity on the part of the Council of State and Territorial Epidemiologists, and the anticipated implementation of State and local health department accreditation.

Number of local health departments reporting that epidemiology and surveillance services for communicable/infectious diseases, chronic diseases and environmental health are provided at least in part by the local health department


Number of local health departments

Comparable Healthy People 2010 Objective: 
Adapted from HP2010 objective
Questions Used to Obtain the National Baseline Data: 

    From the 2008 National Profile of Local Health Departments:


    The 2008 National Profile of Local Health Departments asked the respondents to indicate which organization provided epidemiology and surveillance services in six categories. The categories considered essential to be compliant with this objective were:

    1. Environmental health
    2. Communicable/infectious disease
    3. Chronic disease

    The survey allowed for multiple possible responses from the following options:

    1. Performed by LHD directly
    2. Contracted out by LHD
    3. Done by state government agency
    4. Done by another local government agency
    5. Done by someone else
    6. Not available in jurisdiction
    7. Unknown
Data Collection Frequency: 
Caveats and Limitations: 
This measure does not assess the comprehensiveness of epidemiologic services provided by local health departments. Therefore, these data may not be comparable to measures of epidemiologic services provided by state health agencies.
Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 23-14d in that the data source, the National Profile of Local Health Departments, has revised the questions used to obtain the numerator.

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 2013, the baseline data were revised to only include data on local health departments (not include data on state agencies). The baseline was revised from 64% (2008) to 35.5% (2008). The target was not revised. "State agencies" were removed from the numerator description.
