Characteristics of a Population
Transcript of Characteristics of a Population
-> Census (NSO website)
-> Population surveys (on a section of pop)
-> Registration Data (ex. Marriages)
-> Any other? Sources of Information Rates of Change Summary Statistics States Sex ratio (diff at diff ages, why?)
Labour Force Participation Rate Pt+1 = Pt + Natural Increase + New Migration
Natural Increase = Births less Deaths
Net migration = Immigrants - Emigrants
Crude rates are used (per 2k of population): disadvantages? Female/Male structure
and age structure
really affect these ratios.
Solution? Age specific rates:
(example 3.1) P(n) = P(o)e Exponential Population
Growth Rate rn Very Simple Model! Group discussion: how do populations change over time and with respect to economic growth? Demographic Transitions Sanitation + Health
=> better Infant mortality
=> increase birth rates
=> low fertility rates
(family support lowers + careers + education)
=> longevity http://www12.statcan.ca/english/census01/products/analytic/companion/age/cda01pymd.cfm What to look for: high prop of which age? high fertility? survival rates? longevity?
