The correct answer is: d) All of the above.

A rolling Census model would involve continuous data collection, more frequent updates to population statistics, and greater flexibility in data analysis.

Continuous data collection would allow for more accurate and up-to-date population statistics. This would be beneficial for a variety of purposes, such as planning for elections, allocating resources, and tracking economic trends.

More frequent updates to population statistics would allow for more timely and responsive decision-making. This would be beneficial for a variety of stakeholders, such as businesses, governments, and nonprofits.

Greater flexibility in data analysis would allow for more nuanced and insightful understanding of population trends. This would be beneficial for a variety of research and policy purposes.

Overall, a rolling Census model would offer a number of advantages over the current decennial Census. It would provide more accurate and up-to-date population statistics, allow for more timely and responsive decision-making, and offer greater flexibility in data analysis.
