To solve this problem, we need to analyze the changes in the labor force percentages within the mining and manufacturing sectors between 1887 and 1930 and identify the sector with the greatest increase. We will also determine the likely reason for this increase.
1. Mining Sector Change:
- In 1887, the mining sector had 14% of the labor force.
- In 1930, the mining sector had 26% of the labor force.
- The change in the mining sector is [tex]\( 26\% - 14\% = 12\% \)[/tex].
2. Manufacturing Sector Change:
- In 1887, the manufacturing sector had 20% of the labor force.
- In 1930, the manufacturing sector had 38% of the labor force.
- The change in the manufacturing sector is [tex]\( 38\% - 20\% = 18\% \)[/tex].
3. Determine the Sector with the Greatest Increase:
- To determine which sector had the greatest increase, compare the absolute changes:
- Mining sector increased by 12%.
- Manufacturing sector increased by 18%.
- Therefore, the manufacturing sector had the greatest increase.
4. Identify the Reason for an Increase:
- Historically, the period between 1887 and 1930 saw significant industrialization, especially in developed countries.
Putting it all together:
- The percent of labor force in the mining and manufacturing sectors increased between 1887 and 1930.
- The manufacturing sector increased the most.
- This increase is most likely because of industrialization.
