2005 is the midpoint of a decade that spans three unique, important transitions in the history of human kind. 2000 young people always outnumbered old people. 2000 and up old people will outnumber young people. 2007 rural people will have always outnumbered urban people. 2007 and up urban people will outnumber rural people. 2003 up the median woman worldwide had, and will continue to have, too few or just enough children during her lifetime to replace herself and the father in the following generation. No person who died before 1930 had lived through a doubling of the human population. Any person born in 2050 or later likely to live through a doubling of the human population. The dramatic fall since 1970 of the global population growth rate to 1.1 or 1.2% a year today resulted primarily from choices by billions of couples around the world to limit the number of children born. 1950 the less developed regions had roughly twice the population of the more developed ones. the world's population is projected to reach 9.1 billion, plus or minus 2 billion people, depending on future birth and death rates. Increase of 2.6 billion people by 2050, 6.5 billion people of 2005 exceeds the total population of the world in 1950 was 2.5 billion. Human # currently increase 74 million to 76 million people annually. Birth rates in poor countries are much higher. woman twice as many children (2.9) in the poor countries, rich countries (1.6 children per woman). 51 countries or areas will lose population between now and 2050. The poor countries will have to build the equivalent of a city of more than 1 million people each week for the next 45yrs. Humans are already growing enough cereal grains to feed 10 billion people a vegetarian diet. 1-dimensional quantities that have been proposed as ceilings on human carrying capacity include water, energy , food and various chemical elements required for food production. If water is scarce and energy is abundant. Either that too many humans are already on Earth or that there is no problem with continuing rapid population growth. The most densely settled half of the planet's population lives on 2 to 3% of all ice-free land. if more chemical fertilizers and biocides are applied to raise yields, the rise in food production could put huge strains on the environment. Urbanization threatens frightening hazards from infectious disease unless adequate sanitation measures supply clean water and remove wastes. Cities raise the economic premium paid to younger, better-educated workers whereas the mobility they promote often weakens traditional kin networks that provide familial support to elderly people. Better education in youth is associated with better health in old age. Education in those behaviors that preserve health and promote the stability of marriage. To invest in the economic and social institutions that facilitate economic productivity and social engagement among elderly people.

The year 2005 is the midpoint of a decade that spans three unique, important transitions in the history of humankind. Before 2000, young people always outnumbered old people. From 2000 forward, old people will outnumber young people. Until approximately 2007, rural people will have always outnumbered urban people. From approximately 2007 forward, urban people will outnumber rural people. From 2003 on, the median woman worldwide had, and will continue to have, too few or just enough children during her lifetime to replace herself and the father in the following generation. The century with 2000 as its midpoint marks three additional unique, important transitions in human history. First, no person who died before 1930 had lived through a doubling of the human population. Nor is any person born in 2050 or later likely to live through a doubling of the human population. In contrast, everyone 45 years old or older today has seen more than a doubling of human numbers from three billion in 1960 to 6.5 billion in 2005. The peak population growth rate ever reached, about 2.1 percent a year, occurred between 1965 and 1970. Human population never grew with such speed before the 20th century and is never again likely to grow with such speed. Our descendants will look back on the late 1960s peak as the most significant demographic event in the history of the human population even though those of us who lived through it did not recognize it at the time.

- 2000 young people always outnumbered old people. 2000 and up old people will outnumber young people.
- 2007 rural people will have always outnumbered urban people. 2007 and up urban people will outnumber rural people.
- 2003 up the median woman worldwide had, and will continue to have, too few or just enough children during her lifetime to replace herself and the father in the following generation.
- No person who died before 1930 had lived through a doubling of the human population
- Any person born in 2050 or later likely to live through a doubling of the human population
- The dramatic fall since 1970 of the global population growth rate to 1.1 or 1.2% a year today resulted primarily from choices by billions of couples around the world to limit the number of children born.
- The last half a century saw, and the next half a century will see, and enormous shift in the demographic balance between the more developed regions of the world and he less developed ones.
- 1950 the less developed regions had roughly twice the population of the more developed ones
- 2050 the world's population is projected to reach 9.1 billion, plus or minus 2 billion people, depending on future birth and death rates
- Increase of 2.6 billion people by 2050, 6.5 billion people of 2005 exceeds the total population of the world in 1950 was 2.5 billion.
- Human # currently increase 74 million to 76 million people annually
- Birth rates in poor countries are much higher
- Average woman twice as many children (2.9) in the poor countries, rich countries (1.6 children per woman)
- 51 countries or areas will lose population between now and 2050
- Germany is expected to drop from 83 million to 79 million people, Italy from 58 million to 51 million, Japan from 128 million to 112 million,Russian Federation from 143 million to 112 million
- 1 person in 3 will be 60 years or older in the more developed regions, 1 person in 5 in the less developed zones
- The poor countries will have to build the equivalent of a city of more than 1 million people each week for the next 45yrs
- Humans are already growing enough cereal grains to feed 10 billion people a vegetarian diet
- 1-dimensional quantities that have been proposed as ceilings on human carrying capacity include water, energy , food and various chemical elements required for food production
- If water is scarce and energy is abundant
- Either that too many humans are already on Earth or that there is no problem with continuing rapid population growth
- The most densely settled half of the planet's population lives on 2 to 3% of all ice-free land
- If the intensity of rural agricultural production increases, the demand for food, along with the technology supplied by the growing cities to the rural regions, may ultimately lift the rural agrarian population from poverty, as happened in many rich countries
- if more chemical fertilizers and biocides are applied to raise yields, the rise in food production could put huge strains on the environment
- Urbanization threatens frightening hazards from infectious disease unless adequate sanitation measures supply clean water and remove wastes
- Cities raise the economic premium paid to younger, better-educated workers whereas the mobility they promote often weakens traditional kin networks that provide familial support to elderly people.
