Demographic data & variables

Introduction

Statistical agencies around the world collect data on demographically relevant events such as birth, marriages and deaths.

Below I will talk about demographic data with a focus on sources for Austria and the Austro-Hungarian Empire.

What is demography?

Many major political challenges result from demographic changes. For instance, the pensions systems in many high-income suffer under a declining ratio of economically active individuals per retiree. This trend is caused by declining birth rates and increasing longevity. Or, some middle-income countries (such as China) have to cope with an excess supply of men, which results from a cultural preference for sons and the wide availability prenatal sex-determination technology.

What is population economics?

Population economics (or demographic economics) is the application of economic analysis to demography.

Demographic variables

Give some prelims on crude rates

Fertility

  • Crude birth rate (CBR)
    • Number of live births (B) divided by the mid-year population (P)
    • CBR = (B/P)*1,000
    • Below you can see the CBR for Austria in the period between 1871 an d2014
  • General fertility rate (GFR)
    • Number of live births divided by the mid-year femal population in childbearing age (F)
    • GFR = (B/F)*1,000
  • Total fertility rate (TFR)
    • Measures the fertility of an imaginary group of women who pass through their fictitious reproductive lives subject to the rates of child-bearing experienced by real women in a given year.
    • Below you can see the TFR for Austria in the period between 1970 and 2008
  • Lifetime fertility
  • Illegitimacy ratio

Mortality

  • Crude death rate (CDR)
    • Number of deaths (D) divided by the mid-year population (P)
    • CDR = (D/P)*1,000
  • Sex-specific death rates
  • Age-specific death rates
  • Life expectancy
  • Infant mortality rate

Marriage

  • Crude marriage rate (CMR)
    • Number of marriages (M) divided by the mid-year population (P)
    • CMR = (M/P)*1,000
  • General marriage rate
    • Number of marriages divided by the mid-year population in marriagable age (A)
    • GMR = (B/A)*1,000
  • Total marriage rate (TMR)

Divorce

  • Crude divorce rate (CDR)
    • Number of divorce (D) divided by the mid-year population (P)
    • CDR = (D/P)*1,000
  • General divorce rate
    • Number of divorce divided by the mid-year population in marriagable age (A)
    • GMR = (B/A)*1,000
  • Total divorce rate (TDR)
