Final answer:
There isn't a specific percentage given for full integration of women into male-dominated fields by 2000; however, progress in education and varying contributions in professional sectors reflect improved gender integration over time.
Step-by-step explanation:
The question pertaining to what percentage of women would need to change to a male-dominated field to see full integration in 2000 cannot be answered precisely with the given information. However, examining the progress of women's representation in various professions sheds light on the broader context of gender integration in the workforce. For full integration, one might hypothesize a scenario where the representation of women in various fields mirrors their overall presence in the labor force or the population.
For instance, while women have made significant gains in fields like law and medicine, receiving 47% of law degrees and 48% of medical degrees by 2014, their presence at the top of large companies and in U.S. Congress remains low. Also noteworthy is the decline in the percentage of women in the IT field from 31% to 25% between 1990 and 2020, despite women constituting 47% of the employed workforce. Achieving full integration would necessitate not just educational qualifications but also equitable access to employment opportunities and decision-making positions across all fields.
