As a rule the families of economically active women have had less children than those of the economically non-active women. At least the birth interval between marriage and the first live birth and the two following intervals between the live births have been longer in the case of economically active women than in the case of the economically non-active ones. Those relationships between economic activity, fertility and duration of birth intervals have been modified by source of living, social position, education level, place of residence of the women and in the case of individual farmers also by the size of farm. Economically active married women, for instance, who have lived in the individual farmes, they bore more children (than the economically non-active ones. Women living from private farms have had the bigest families; the same or slightly smaller families have been observed in the socialized agriculture and forestry; much smaller in industry, construction, commerce and transport and the smallest families have had those who have lived from non-productive services.polinfo:eu-repo/semantics/openAccessArtykuł
