Answer:
1. Aging
2. Increased immigration
3. Unequal distribution of income
4. More women obtaining degrees
Step-by-step explanation:
1. Aging: the reduced fertility rate as well as low natality has caused a major shift to the elderly population with time because there is no increased population growth
2. Increased immigration: Currently there is a major decline in white (non-hispanic) population and an increased population shift towards the hispanic race due to immigration and procreation. There is also an uprise in the Asian population in the USA.
3. Unequal distribution of income: this is majorly caused by a higher demand fro high-skilled workers, immigration, competition from emerging economies as well as a poor regulation of the markets.
4. More women obtaining degrees: according to the U.S news, USA has seen an increase in women obtaining professional degrees (10.6 million) than men (10.5 million). Although the increase in women obtaining more degrees and more involvement in economy growth, women are still underpaid compared to their male counterparts.
