POPULATION GROWTH

POPULATION GROWTH All members of the same species living in the given area and time, and actually/potentially interbreeding BASIC CONCEPT OF POPULATION GROWTH Sex Ratio & Age Distribution Together they tell how population grow Sex Ratio Relative number of males and females in a population Age Distribution Number of individual of each age in population POPULATION

POPULATION GROWTH Study of populations, their characteristics and changes Demographers Study population size Density and distribution Age structure Sex ratio Birth rate Death rate Immigration and emigration rates Demography Demographer

POPULATION GROWTH Change in population size Factors Affecting Population Size Change in Population = (birth – death) + (immigrants – emigrants) (Crude) Birth rate The number of individuals born during a specified time interval When the birth rate is higher than death rate, more people are born than are dying so the population grows Natural Increase 2024 Total Population: 8.2B Natural Decrease When the death rate is higher than birth rate.

POPULATION GROWTH Migration Population Movement -Permanent change of residence of a person/ group . Emigration - movement of people out of a country. Immigration - movement of people into a country. Push Factor No Job Opportunity Poverty War Environmental Disasters Pull Factor Economic opportunity Political Freedom Better standard of living

POPULATION GROWTH Children in labor force Cost of raising and educating children Urbanization Education level & employment for women Infant mortality rate Religious beliefs, customs, and tradition Average marrying age Availability of birth control and abortion FACTORS AFFECTNG BIRTH RATE TOTAL FERTILTY ATSARA

POPULATION GROWTH Early Marriage -foster high fertility rates Lack of Education –opportunities for women reduced their options. When Level of education increases, fertility rates decreases. Most important factor is the ability of women to control the size of the family Access to birth control is key. MAJOR FACTORS DETERMINING FAMILY SIZE the role of women in society

POPULATION GROWTH Family planning Improve health care Elevate the status of women Increase education Involve men in parenting Reduce poverty Sustainability Equal distribution of wealth CUTTING HUMAN POPULATION GROWTH

POPULATION GROWTH POPULATION & RESOURCE USE Population and resources have a strong relationship with one another. The growth and decline of population affects the availability of natural resources. At the same time, the availability of natural resources affects the trends seen in population. Rapid population growth continues to be a major underlying force of environmental degradation and a threat to sustainable use of natural resources. It reduces the quality and quantity of natural resources through overexploitation, intensive farming and land fragmentation. IMPACT OF POPULATION TO NATURAL RESOURCES

POPULATION GROWTH ECOLOGICAL FOOTPRINT The amount of biologically productive land and water needed to indefinitely supply the people in a particular country or area with renewable resources and to absorb and recycle the wastes and pollution produced by such resource use. Maximum number of individuals of a given species that a particular habitat can support without depleting its resources. CARRYING CAPACITY
