Final answer:
Column 1 in the chart represents three key demographic factors: population growth rate, fertility rate, and life expectancy. The entry negative 0.10 for Japan indicates a slight population decline in that country.
Step-by-step explanation:
The demographic information displayed in the chart and described in Column 1 represents three vital statistical categories relevant to population studies: population growth rate, fertility rate, and life expectancy. These are common metrics that demographers use to assess the characteristics and trends of a population. Specifically:
- The population growth rate indicates whether the population of a region is increasing or decreasing and at what rate.
- The fertility rate refers to the average number of children a woman is expected to have during her childbearing years within a specific population.
- Life expectancy measures the average length of time individuals within a population are expected to live.
Given this information, we can determine that Column 1 in the student's chart represents these demographic factors. The entry negative 0.10 for Japan specifically refers to its population growth rate, indicating that Japan's population is, in fact, decreasing slightly.
