Access to Safe Water

  • Nearly 1.1 billion people (20% of the world’s population) lack access to safe drinking water.

  • Kills almost 4,500 children per day.

  • Worst “water stressed” countries in Sub-Saharan Africa and South Asia.

  • Climate and geography, lack of water systems and infrastructure, inadequate sanitation, high levels of arsenic and fluoride in drinking water.

  • Women and young girls trek as much as six miles everyday to retrieve water.

  • Obstacle to progress and development.

  • Centrifugal forces: impel functions to migrate from central zone beyond it periphery

  • Centripetal forces: hold certain function in central zone and attract others

Immigrants as a Percentage

Centers of Population http://www.census.gov/geo/www/cenpop/MeanCenter.html

Mean Population Point

Median Center of Population

The numerical center of population, is in no sense a center of gravity. In determining the median point, distance is not taken into account and the location of the units of population is considered only in relation to the intersecting median lines - as being north or south of the median parallel and east or west of the median meridian.

The center of population is the point at which an imaginary, weightless, rigid, and flat (no elevation effects) surface representation of the 48 conterminous states and the District of Columbia (or 50 states as appropriate to the computation) would balance if weights of identical size were placed on it so that each weight represented the location on one person.
