• Standardized set of metrics that characterize the built, social and natural environment
• Nationally consistent at the block group scale • Support analyses on a variety of environmental
indicators as part of RWJF’s Culture of Health initiative

PROJECT PURPOSE
• Project Overview • Variable development
– Types of Variables – Variable Criteria
• Composite Variables – Examples from the Healthy Communities Atlas
• Applying the Data – Synergy with EPA National Model
• Predicting Health Impacts and Related Costs

ADVISORY COMMITTEE
• Feedback on strengths and weaknesses of initial selection of data sources – Potential areas of cautions
• Review methods utilized to operationalize key variables
• Recommend potential end users and ways to further strengthen connections with other efforts underway to disseminate national data
6
ROLE OF ADVISORY COMMITTEE
• Types of Variables – Existing nationwide variables (e.g. SLD 1,
EnviroAtlas 2) – Composite measures – Variable weighting – Region-specific new variables at smaller spatial scale
• Frequent updates of variables at regular intervals where available

COMPOSITE
Variable Examples: San Diego Health Communities Atlas
• UD4H is developing a public health and activity plug-in module for scenario planning tools
• Plug-in will connect open scenario planning tools via an API to expand the range of platforms for use
• The NED provides a nationally available set of data inputs using the EPA health & activity model
