Birth deficit
In demography , one speaks of a birth deficit or death surplus when the death rate in a state , city or region is higher than the birth rate, i.e. the number of live births in a defined period is lower than the number of deaths in the same period.
The natural population development , i.e. the difference between births and deaths, is "negative" in such a case. If the birth deficit is not compensated for by a “positive” spatial population development (net migration), the population will decline. A birth deficit also increases the old-age quotient of a society.
Many countries, including Germany , have had a clear birth deficit for years, which has lasting consequences for population development . The reasons for the emergence of the birth deficit, the introduction of are birth control pills ( Pillenknick ), the trend towards nuclear families , a changing roles in society, the later age at marriage and lack of child care facilities given.
If, on the other hand, the natural population development is positive, one speaks of a birth surplus .
