Total Fertility Rate (TFR) |
|
TFR is the number of children a woman has received at the end of her fertile period. |
|
TFR is directly taken from the SRES population projections made by IIASA (IPCC, 2000) |
|
Life expectancy |
|
Life expectancy is the mean number of years a newborn may expect to live given the present mortality experience of a population |
|
Life expectancy is directly taken from the SRES population projections made by IIASA (IPCC, 2000) |
|
Households |
|
Number of households is calculated from the average regional number of persons per household and total population |
|
In all scenarios and regions the number of persons per household will converge to 2.4-2.7 persons. |
|
Population and population growth |
|
Population represents total population (male + female); population growth is obtained from the population in a certain year and that of the preceding year |
|
Total population and population growth are from the SRES population projections made by IIASA (IPCC, 2000) |
|
Urbanization |
|
Fraction urban population of total population |
|
The fraction urban population is based on UN projections (UN, 1998) up till 2030, and after that an increase to 90% in the year 2100 is assumed for all regions |
|
Dependency ratio |
|
The ratio between the population considered to be dependent (below 15 years of age and 65 years and over), and the working-age population (15-65 years). |
|
The dependency ratio is taken directly from the SRES population projections made by IIASA (IPCC, 2000) |
|
Human Poverty Index (HPI) |
|
HPI is composed of income (GDP per capita), life expectancy, food consumption, access to safe drinking water, and health services |
|
For GDP per capita the WorldScan scenarios are used |
| Life expectancy at birth is taken directly from from the SRES population projections made by IIASA (IPCC, 2000) |
| Food consumption will converge to levels of 3000-3500 Kcal per person per day finally resulting in the elimination of malnutrition |
| Full access to safe drinking water is assumed to be achieved in the next 2-3 decades |
| Health services are related to income and are assumed to improve in low-income regions along with incomes to reach 100% coverage corresponding with levels of high-income regions |
|
Human Development Index (HDI) |
|
HDI is calculated from income (GDP per capita), (female) literacy and life expectancy at birth |
|
For GDP per capita the WorldScan scenarios are used, |
| All regions are assumed to have female literacy levels above 70% in 2025, 80% in 2050 and full coverage after that |
| Life expectancy at birth is taken from the SRES population projections made by IIASA (IPCC, 2000) |
