To determine which element best indicates that this chart represents census data, we should analyze the characteristics and contents of the chart in detail.
We are given information about Bangladesh and Utah, including:
1. Population (in millions), 2004
2. Total area (in square miles)
3. Population density (population per square mile)
4. Birthrate
5. Fertility rate
Now let's consider each of the options:
A. The chart compares two countries.
- While the chart does provide a comparison between Bangladesh and Utah, it doesn’t inherently point to it being census data. Comparative data can come from various sources, not just a census.
B. The labels are easy to read.
- Clear and readable labels are important for any kind of data presentation, but this characteristic alone does not indicate it is census data.
C. There is no bias in the chart.
- Lack of bias is a general quality of any good data representation but does not specifically point to census data.
D. Population numbers and population density are listed.
- Census data typically includes comprehensive demographic information such as population numbers and density because such metrics are key components of a population survey. Census data is known for providing detailed and accurate counts of various population metrics.
Given that population numbers and population density are fundamental elements typically collected and reported in census data, the best indicator that this chart is census data is:
D. Population numbers and population density are listed.
This option directly points to the core function of census data, which is to enumerate population details and demographic statistics.
