Answer:
The reason for migration can be attributed to segregation and better life.
Explanation:
Northern and Eastern migration: It was the relocation to cities of the West, Midwest and North due to unpleasant segregation laws and unsatisfactory economic opportunities which resulted in the movement of blacks to head north, where industrial workers were needed.
Bantu Migration: The reasons for the Bantu migrations were:
• Dried state of the Sahara grasslands which resulted into people that practiced agriculture to move in search of water and fertile land for farming.
• Increase in population which created pressure on resources causing movement in search for new land.
• Tribal wars resulted in defeated tribes to relocate for safety.
• Expansion of their iron-working after its discovery also caused migration.
The effects of Bantu migration include positive and negative effects. Positive effects include:
• Introduction of iron working
• Increase in food production.
• Introduction of new crops such as bananas and yams.
Negative effects include:
• Depopulation which was due to constant attacks for land by the Bantu against people in East Africa.
• Loss of culture: The loss of culture was a result of cultural absorption and intermarriage with other tribes.

This is because when people had traveled with Marco Polo they had seen all of the opportunity that they were missing when they weren't trading what they had traded with the Orient when they first started.

<span>Congressional staff increased greatly in the 20th century due to the shift in politics from grassroots to higher levels of lobbying, groups and special interests. The congress person was not only invested in their district but in those special interest groups requesting meetings and events with the congressperson. By increasing staff, they would be able to learn more about these groups and lobbyists so they could make a more informed decision. It also allowed the staff to deal directly with the public. A congressman in the early 20th century would only have in person visits and the occasional phone call, but by the end of the 20th century, the congressperson would have contact via appointment, call, letter, email and even rudimentary instant contact via Instant Messenger and sites like Myspace.</span>
