Factors associated with trends in infertility: (1000 words) Marriage trends, trends in family formation - From the literature. Role of voluntary and involuntary factors (1000 words) Is infertility due to infertility, circumstances or choice? - Taken from literature. The risk of not having a child increases with the delay in the first birth. The duration of reproduction is also reduced, as is the number of children. Changes in educational attainment also lead to delayed fertility (Olah and Bernhardt 2008). A high tolerance for childlessness is found in the dominant postmodern values ​​in Sweden which propagate the importance of leisure and friends in life and children, although considered important, are not necessary for a fulfilled life (Olah and Bernhardt 2008). Swedish women with higher education have higher rates of infertility than others (Olah and Bernhardt 2008). Sweden observed the highest female labor force participation rate in Europe and was considered the main reason for the decline in fertility in the 1960s and 1980s in Sweden, as well as post-birth. modern values ​​and the use of contraception that have given women greater control over reproduction (Olah and Bernhardt 2008)). Contrary to the above, Sweden, which is the precursor of the second demographic transition, observed the highest fertility trends in Europe and the lowest in Sweden, which fluctuated greatly in the 1960s and 1970s ( Olah and Bernhardt 2008). With the dominance of postmodern values ​​in this increasingly secularized society, Sweden boasts one of the highest ideal family sizes in the European Union and the rate of infertility is relatively low (Olah and Bernhardt 2008). Bernhardt 2008). Sweden also has the highest labor force participation rate in all of Europe and the education level of women is also as high as that of men (Olah and Bernhardt 2008). Swedish family policies play an important role in maintaining a high level of fertility, which is based on equality between social groups and sexes (Olah and Bernhardt, 2008). Eligibility for parental leave and other benefits is linked to labor market participation and family policies therefore play an important role in shaping fertility rates (Ola and Bernhardt 2008). Some researchers attribute improved economic status and educational attainment to delays in marriage and childbearing and increases in divorce and single motherhood (Danziger and Ratner 2010) please refer further to the source Claudia Goldin (2006) describes the Women's increased engagement in the economy as the most notable change in labor markets in the 20th century.
