			* '''<u>Population dynamic</u>'''The population is divided in one year age-range from 0 to 100+ year old, with each year the population gets one year older. There is an amount of newborns that will represent the 0 age range, and there is also a certain amount of deaths per age category.
			* '''<u>Birth rate</u>'''According to the United Nation definition, the age-specific birth rate is the "number of births to women in a particular age group, divided by the number of women in that age group". In our model, we look at the birth rate for the 15-49 age group, the young active population in childbearing age. The birth rate depends on Gross World Product, population and knowledge
			* '''<u>Death rate</u>'''The death rate is the number of deaths divided by the number of persons in a specific age category and year. Similarly to birth rate, the death rate per age category and year depends on Gross World Product and on population. Death rate is also impacted by climate in four principal ways, global warming affects crops by reducing yields and the micro/macronutrients contents of cereals, favors allergens and vector-borne infectious diseases such as malaria or dengue, increases risks of diarrheal diseases due to heat waves causing reduced access to safe water, and increases probability of heat waves that causes higher mortality related to cardiovascular or chronic respiratory diseases<sup>[[/github.com/os-climate/witness-core/blob/main/climateeconomics/sos wrapping/sos wrapping witness/population/documentation/population discipline.md#user-content-fn-2-3a768df8d3cd5ed80ed3cf35357c68ad\|3]]</sup>. It is modelized following excess mortality function associated with climate change
			* '''<u>Working age population</u>'''The working age population is the population in age to work, it is the sum of population in the 15-70 age range. It's used by macro-economy to define labor capability together with education
			* '''<u>Life expectancy</u>'''Life expectancy at birth is the age-averaged proportion of surviving people, which is depending on GDP per capita.
