Westward expansion's impact on population is best described as

• A. Population growth
• B. Population decline
• C. No change
• D. Random fluctuation

Answer: (A)

The key idea here is that moving west brought a strong increase in how many people lived in those regions. As Americans pushed into the West during the 19th century, many settlers arrived in areas that offered new land and opportunities for farming, mining, and later developing towns and cities. Government policies, like the Homestead Act, opened up land to ordinary families, and the expansion of the railroad made far-western territories more accessible. All of this encouraged migration, supported larger family sizes, and led to the rapid growth of Western communities and eventually new states. While there were hardships and regional variations, the overall impact was clear population growth in the West.
