Since 1998, the National Longitudinal Survey of Public Health Systems (NLSPHS, as of 2018 NALSYS) has followed a nationally representative cohort of U.S. communities in order to study the implementation and impact of multi-sector population health activities.  The survey captures information about the types of health improvement activities that are implemented in U.S. communities, and the array of organizations that contribute to these activities.  By collecting this information consistently in more than 500 U.S. communities over a span of 20 years, the NALSYS has become the nation’s only national, longitudinal source of information about the actions that local communities undertake to protect and improve the health status of their residents.
