This tool allows you to estimate the minimum safety infrastructure required for a specified number of people. Toggle the population slider or search for and click on a city name. Once a city is entered, the value in the population slider is ignored. The estimates here represent the minimum – not optimal – quantity of services required for a given population and do not account for service quality. They are derived from the best data available and may underrepresent the real need in your community.
