  • [Economics]
    A central region in an economy, with good communications and high population density, which conduce to its prosperity. The core is contrasted with the periphery, outlying regions with poor communications and sparse population. Some regional economists argue that the differences between core and periphery tend to increase as migrants and investment are attracted to the core. Large populations give core regions considerable voting power, which means that government policies tend to be more responsive to core than to peripheral needs.
