• Global Population- population exist widespread around the planet
• Demography- the study of human population
• Demographic Transitions- from high birth and death rates toward to ow birth and death rates from primative to modern conditions of society
• Four stages of the classical demographic transition- 1st stage Pre-Transition Phase, 2nd stage Early transition phase, 3rd stage Late transition phase, 4th stage Post-Transition Phase
• Pre-transition phase- the population dynamics is characterized by high birth rates and high fluctuating death rates
• Primitive Stability- population growth is kept low and fluctuating.
• Early Transition Phase- death rate begins to fall why birth rate remains high
• Late transition phase- gradually decreasing rates and narrowing margin to the low death rate
• Fertility Transition- population growth deccelerates
• Post-transition phase- population net growth is almost zero
• Modern Stability- is attainable if it is backed by strong economics, high levels of education, better healthcare, high proportion of working women, and a low fertility rates have dropped significantly low which is limited to two children per women
• Population profile or Population age structure- summarize the number of individuals of each age group in the population
• Age Pyramids- top-heavy as it is toward older, post productive age groups
• Responsible Parenthood and Reproductive Health Law
• Ecological footprint- summarizes the amount of and water area required by each person city or nation to produce all the resources consumed
• High income nations- referred to as the developed countries compares 1.13 billion that include wealth nations and regions
• Middle income- moderately developed countries have approximately 4.92 billion
• low-income- developing countries that have 1 billion inhabitants
• A stable population then has zero population growth.
• zero population growth = high birth rate - high death rate
• zero population growth = low birth rate - low death rate
• Neolithic Revolution - the revolution that saw the development of technology needed to plant and harvest crops, and to domesticate animals
• Medical revolution - the revolution of health care, where from the 17th century onwards, medical knowledge and practice improved
• Louis Pasteur is renowned as the father of microbiology
• Robert koch is considered as the founder of modern bacteriology
• Industrial Revolution - The period of rapid economic growth and social change in the 18th and 19th centuries.
• Environmental Revolution - the revolution where new "green technology" is innovated and where slowly switching to sustainable farming practices
• Green Revolution - A period of rapid agricultural development in the 1960s and 1970s, sought increase in production, improved and increased the yield of crop varieties
• Biocapacity -is the estimate of a biologically productive area to generate on-going supply of renewable energy
• Inequalities within countries demonstrated by differences in economic prosperity heavily influence population growth as it affects the quality of living, development, and the state of environment
