Answer
The study is a **cross-sectional study**.
Solution
The scenario describes a **cross-sectional study**. Here's why:
- **Cross-Sectional Study**: This type of study observes a defined population at a single point in time or over a short period. It assesses both exposure and outcome simultaneously. In your example, polling 10,000 citizens in a single month to obtain current employment data fits this description perfectly.
- **Retrospective Study**: This type looks back at data from the past. It involves analyzing existing data to find correlations between exposure and outcomes.
- **Prospective Study**: This study follows participants into the future to observe outcomes, often over an extended period.
Given the definitions:
**Answer: B. Cross-sectional**

Simplify this solution Beyond the Answer
When the town polls 10,000 citizens this month, it captures a snapshot of employment data at a specific point in time, which makes it a cross-sectional study. This method allows for an analysis of the employment status of a large group of people simultaneously, offering insights into trends and current conditions. Diving deeper, retrospective studies look back at past data to find correlations or patterns. In this case, since the data is gathered right now and not reliant on historical records, we can rule out option A. So, the answer here lies clearly within the realm of cross-sectional analysis.
