# Population Dynamics ## Calculating Growth Rate * **Growth rate (%) when given numbers:** [(# Births - # Deaths + # Immigrants - # Emigrants) / Total pop.] x 100% * **Growth rate (%) when given crude rates (numbers per 1,000 people):** (CBR - CDR + crude immigration - crude emigration) / 10 * **"Rule of 70": Doubling time (in years):** 70 ÷ growth rate as a % * **Net migration:** Immigration - Emigration (in either numbers or crude rates) ## Module 18: Human Population Dynamics ## Socioeconomic Factors Influencing Demographic Parameters * **Access to quality healthcare, including prenatal care** * **Access to healthy food and clean water** * **Education and freedom for people with uteruses** * **Access to family planning services and contraception** * **Cultural norms, expectations** * **Social bias and prejudice:** Affect many things differently for various groups within a country (BIPOC, poor people, etc.) * **Sanitation** * **War** * **Pollution** * **Disease** * **Theory of demographic transition:** (see my comparison table)
