In creating planned communities ("new towns"), it is important to determine the appropriate population and geographical size. While in earlier years small towns were considered appropriate, by the 1960s, 60,000 inhabitants was considered the size necessary to support a diversified job market and an adequate shopping center and array of services and entertainment. Appropriate size of governmental units for revenue raising also is a consideration.Harry Ward Richardson, Urban economics, Dryden Press, 1978, pp. 107, 133, 159 .
