Final answer:
From the provided table, we can deduce that 1) North Dakota has more counties among the fastest-growing than any other state, and 2) Sumter County, Florida, has the highest population among the listed counties. However, in terms of actual net gain, Fort Bend County in Texas has the highest numerical increase.
Step-by-step explanation:
The student's question involves analyzing a table to derive two conclusions based on population data of the fastest-growing counties in the United States. From the table provided, we can draw the following conclusions:
- North Dakota had more counties in the fifteen fastest-growing counties than any other state. This is evident as there are multiple counties such as McKenzie, Williams, Stark, Dunn, and Divide counties from North Dakota listed in the table.
- Sumter County, Florida, had the highest population among the fifteen fastest-growing counties, based on the populations provided in the 2014 column. However, if we were looking for the most populous county regardless of the growth rate, then Fort Bend County, Texas, would take that title.
It is important to note that the term 'highest net population gain' mentioned in the student's question refers to the absolute increase in numbers, not the percentage change. Therefore, although McKenzie County had the highest percentage growth, it did not have the highest net gain in population. That title would go to Fort Bend County, TX, which grew by 30,784 from a much larger base population.
