How has the increase in participation of women in the U.S. labor force since the 70s affected GDP? How has the increase in participation of women in the U.S. labor force since the 70s affected GDP? Solution First go through some good data to make a rough picture of female participation in the US labour force. I\'ll provide you with some useful links too. In 1972, some 44% of women in the US participated in the workforce. In 2012, the figure was almost 58%, in 2015 it could have risen even more. http://www.dol.gov/wb/stats/LForce_Race_Hispanic_Ethnicity_72_12_txt.htm So you have a considerable proportion of working women in 2012. Next, have a look at the occupations women participate in. You will notice that some top occupations like in administration, secretarial, law, financial management, education, operations research and analysts, are actually employed by a considerable propeortion of women. Women also share stage in medical and biological science. You\'ll find this data here: http://www.dol.gov/wb/stats/Highest-lowest-paying-occupations.htm Women also earn a median salary of $706 annually according to the data collected in 2013, with men earning a $100 more, so you have there a more or less equal share as far as salaries are concerned. Now what is GDP? Its a measure of the total produce the country has achieved annually. Now because you have more than 50% of women population already employed with respectable salaries, their share in the GDP naturally comes to light. Now, GDP is effected by the occupations you take into consideration. The data above clearly shows women in managerial and top occupations so you have American GDP considerably effected by women labour.
