Explanation:

1. For the largest population: Look for the highest single data point across all lines; New York's 2006 point is the highest.
2. For West Virginia's smallest population: Find the lowest point on the West Virginia line, which is in 2001.
3. For matching populations: Identify the year where West Virginia and New York lines intersect, which is 2004.
4. For largest single-year decrease: Compare the steepest downward slopes; Alaska's drop from 2006 to 2007 is the most drastic.
5. For largest total increase (2001-2007): Compare each state's 2001 and 2007 values. Alaska's 2007 value is far higher than its 2001 value, a bigger change than the other states.
