摘要：This paper i d e n t i f i e s and examines i n d u s t r i a l and occupational changes t h a t have accompanied population growth i n Texas. According t o the 1960 U.S. Census d e f i n i t i o n s f o r county size, Texas counties were grouped as metropolitan, urban-nonrnetropolitan, and rural-nonmetropolitan. Employment i n 13 i n d u s t r i a l and 9 occupational categories was used t o measure sustenance d i f f e r e n t i a t i o n . I n d u s t r i a l employment (SDI) d i v e r s i f i e d i n both the s i x t i e s and seventies as nonrnetropolitan counties became more s t r u c t u r a l l y homogeneous. Occupational employment (SDO) decreased i n operative, labor, and farmer-farm worker jobs and increased i n sales, c r a f t s , c l e r i c a l , and professional-technical-kindred jobs. A d d i t i o n a l l y , i n 1980 SDI and SDO were markedly less correlated than i n previous years, suggesting a change i n previous s t r u c t u r a l r e l a t i o n s h i p s between industry and occupation. Migration rates were much more h i g h l y correlated with SO1 than with SO0 over the 20 years.
