The Changing Spatial Concentration of America's Rural Poor Population*

The Changing Spatial Concentration of America’s Rural Poor Population

This paper documents changing patterns of concentrated poverty in nonmetro areas. Data from the 1970 through 2000 U.S. Census Summary Files reveal the changing shares of poor people and children living in rural counties with disproportionately poor populations. Nonmetro poverty rates – both overall and for children – declined more rapidly than metro rates in the 1990s. The 1990s also brought la...

Changing Regional Spatial Structure of the Population and Activity The Case of West Azerbaijan Province, Iran

Functional and structural changes of regional system are ongoing spatial changes that form patterns of spatial organization, depending on dominant regional forces and factors. Spatial structure of West Azerbaijan province experienced significant changes during 15 years; thus, the present research aim to investigate the manner of spatial distribution of two variables of population and activity, ...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Population Dynamics Are Changing the Profile of Rural Areas

Spatial analysis of comparative advantage of major occupational groups of rural population in Iran

Introduction Regarding the fact that economic activities, in particular, and resources and facilities, in general, are poorly concentrated in terms of spatial distribution, every area requires a particular program corresponding to its specific conditions. In this way, before doing everything we need to identify the past and present situation of different regions based on appropriate scientif...
