Geografski osobenosti na rajdaemostta i reproduktivnoto povedenie na naselenieto v NR Bâlgariia. (Geographical peculiarities of birth-rate and population reproductive performance in Bulgaria)
Birth-rate has reduced to 14,3 / in 1980. The author applies the model of V. Borisov hypothetical minimum of birth-rate. Minimal birth-rate coefficients by age groups were derived with the help of a mathematical model of reproduction process
. The low birth-rate necessitate an active demographic policy, which is to have effect on reproductive performance. It should be carried out on two levels national and regional.
Movement of crude birthrates, natality by nationality, birthrates of agricultural and non-agricultural population, extramarital natality, live birth with professional assistance, infant mortality, liveborn children by sequence of birth.
Simplified birthrate estimates under nonstable conditions
A simplified birthrate estimate that does not require reference to models of life tables or stable populations is suggested and some of its applications are illustrated.

in fertilyty which are reflected not only in the patterns of variation in overall fertility, marital fertility and proportions married but also in the degree to which these indices have changed between 1926 and 1971. Recent variations in the birthrate
are indicative of the balance between further declines in marital fertility and increases in proportion married and it is likely that the birthrate will continue to fluctuate during the next few years as a result of these two contrasting trends.
