What is a common data limitation in low-income regions that can hinder policy evaluation?

• A. Excess redundancy of datasets
• B. Uniform national coverage
• C. Data gaps across regions
• D. Real-time, highly accurate data

Answer: (C)

The main idea here is that not having enough data across different places is a major hurdle for evaluating policies. In many low-income regions, data collection isn’t consistent from one area to another. Some districts may have little to no up-to-date information, indicators may vary in what they measure, and surveys may be irregular. When data are missing or very sparse in some regions, it’s hard to see how a policy performed in each area, to compare regions, or to identify where a program is working well versus where it isn’t. This limits the ability to estimate true impacts, allocate resources effectively, and generalize findings beyond the areas with good data. Excess redundancy of datasets isn’t the typical problem here; having too many overlapping datasets can even complicate analysis, whereas the common obstacle in these contexts is gaps and uneven coverage. Uniform national coverage and real-time, highly accurate data are ideal but are rarely achieved in low-income settings, so they don’t describe the usual limitation as well as data gaps across regions do.
