Taking steps to provide a built environment that
  promotes physical activity, increases access to nutritious food
  and reduces exposure to safety risks and environmental hazards
  benefits all segments of the community. However, specific subsets
  of the general population may be especially vulnerable to
  particular health effects and may benefit most from certain
  actions. Conducting an initial health assessment to determine
  community needs and trends constitutes an important first step in
  understanding their needs.
  For example, young people have particularly high rates of
  overweight and obesity compared with adults.65  Similarly, residents in
  predominantly low-income communities may have less access to
  fresh, healthy food.66
  Determining the most important health concerns within the
  community may not be obvious. There are a number of ways that
  local officials can gather information to assess health needs and
  trends. Potential sources of information include:
  - Local public health officers and health departments
  
- State and federal health agencies, such as the California
  Department of Public Health and the Centers for Disease Control
  
- Local universities, including university medical research
  centers
  
- Local hospitals, clinics and associations of health
  professionals
  
- Community-based organizations working on health issues
