Final answer:
Household sizes can be determined by analyzing the trend depicted on the graphs from 1970 to 2000.
Step-by-step explanation:
In order to interpret the graphs and determine if household sizes generally increased, decreased, or stayed the same from 1970 to 2000, we need to analyze the data represented. If the graph shows an upward trend indicating an increase in household sizes over the years, then the answer would be that household sizes generally increased. Conversely, if the graph shows a downward trend indicating a decrease in household sizes, then the answer would be that household sizes generally decreased. Lastly, if the graph shows a relatively flat line, it would suggest that household sizes stayed the same during that time period.
