In Sweden, demographers studied labor force participation of 1 child mothers based on data from interviews with 4300 women aged 20-44 in 1981. In 1982, 2 million women and 2.3 million men were employed in Sweden, but 47% of the women worked part time ( 35 hours/week) while only 7% of the men did. The research showed that women are becoming more and more apt to work part time after the birth of their 1st child (prior to 1967, mean 12%; 1968-1974, mean 22%; 1975-1980, mean 35.7%). In addition, 1 child mothers who return to work full time following the 1st birth have a tendency to reduce working hours. Therefore, full time employment for 1 child mothers has become more temporary. On the other hand, 1 child mothers who work part time are more inclined to continue working part time until the next child is born. A positive correlation exists between length of work experience prior to 1st birth and part time work, especially if the length is 5 years. Further, the work experience of women with a low level of education increases the probability of part time work, and less so for highly educated women. Women who have worked for a while and have a more established position in their place of employment are more likely to find and keep a part time job after 1st birth than are women who do not fit this category. This new option for Swedish women of caring for the 1st child and performing domestic duties, and yet still be able to have 1 foot in the door by working part time, is called the combination strategy. Women who are opting for the combination strategy include women, who if lived in the past, would have clearly chosen the homemaker strategy of the career strategy. Further analyses, such as work-life transitions of 2 or child mothers, are needed.
