The category of newly industrialized country (NIC) is a socioeconomic classification applied to several countries around the world by political scientists and economists. NICs are countries whose economies have not yet reached a developed country's status but have, in a macroeconomic sense, outpaced their developing counterparts. Another characterization of NICs is that of countries undergoing rapid economic growth (usually export-oriented). Incipient or ongoing industrialization is an important indicator of an NIC. In many NICs, social upheaval can occur as primarily rural, or agricultural, populations migrate to the cities, where the growth of manufacturing concerns and factories can draw many thousands of laborers.
