Study Notes

Demography

Demography, in a narrow sense, focuses on quantitative relationships between demographic phenomena.
Broadly, it encompasses the study of population's interrelationship with socioeconomic, cultural, and other variables.
John Graunt's empirical mortality observations were termed "natural and political" observations, highlighting demography's mathematical, biological, and social nature.
Scholars from various disciplines have historically contributed to the development of population studies.

Mathematics: Crucial for quantifying population data (size, growth, structure, components).
Statistics: Essential tool; probability theory aids mortality analysis; actuarial science is used in life table construction.
Biology: Closely linked; fertility is biologically determined (female, specific age range); age/sex mortality differentials are biologically determined; sex ratios at birth are biologically determined.
Sociology: Davis connected fertility to attitudes and social institutions, population change to social/economic change, labor force to population structure and social organization, and family to demographic behavior; Broom and Selznick considered population a key element in sociological analysis.

Migration Terminology

Midpoint population: (Beginning population + ending population) / 2
Migrant: Person moving permanently between political areas.
Migration counterstream: Migration opposite a main stream.
Migration stream: Migrants sharing origin and destination.
Migration: Permanent residence change across defined political/statistical units (has time and space dimensions).
Mover: Person changing residence.
Nationality: Present citizenship, origin country (may be extinct or with different boundaries).
Natural fertility: Fertility without deliberate control.
Neonatal mortality rate: Newborns' deaths (first month) per 1000 births.
Net immigration: Immigrants minus emigrants.
Net migration: In-migrants minus out-migrants (often includes international and internal).
Net nuptiality tables: Account for mortality and marriage; show marriage and death rates' impact on single persons, average marriage age.
Net reproduction rate (NRR): Average daughters born to a hypothetical cohort, considering mortality.
Non-migrant: Non-movers plus local movers.
Occupation: Work type during a reference period, regardless of industry or status.
Old-age dependency ratio: Proportion of adults over 65 relative to the working-age population (15-64).
Order-specific divorce rate: Divorces of a certain order per 1000 persons married/divorced that many times.

Contraception Methods

Implants (Norplant): Hormone-filled capsules inserted under the skin; high effectiveness (99.9%); Norplant I (six capsules, five years) vs. Norplant II (two capsules, three years).
Emergency Contraception Pill (ECP): Reduces pregnancy chance by 75% within 72 hours of unprotected sex; requires physician; high hormone levels prevent ovulation; alters uterine environment.
Vaginal Ring (Nuva Ring): High effectiveness (95-99%); monthly insertion; releases hormones; various benefits (period regularity, less pain).
Tubal ligation: Female sterilization (permanent, but reversible).
Vasectomy: Male sterilization; vas deferens ligation; high effectiveness (0.1% failure rate), faster recovery than tubal ligation.

Migration's Effects

Migration can lead to agricultural commercialization due to favorable trade and market expansion.
Technological changes and remittances from migration contribute to agricultural monetization and mechanization.
Effect on rural fertility: Migration influences income distribution (a fertility determinant); impacts sex ratios; affects family size due to separation; influences values and fertility norms.
Consequences for urban areas: Economic effects are complex; analyzed by comparing employment, income, occupational structure, savings, capital formation, etc., before and after migration.
Effect on wages and unemployment: Migrants may increase employment or lower wages; increased labor supply may stimulate investment and industrialization.
