Question About Health Center POI Data Trends (2021-2023)
We are using mobility and foot traffic data to identify the number of unique POIs for certain business types. While comparing the number of health centers across different years using the same NAICS code, we noticed a significant increase from 2021 to 2023.
When examining a specific CBG, we found over 7,000 health centers in that area, with many locations only one meter apart based on their latitude and longitude. However, when applying the same NAICS code method to pharmacies and hospitals, we did not encounter a similar issue.
Would it be possible to get more information on how the POI data is collected, particularly for health centers? Also, any insights into what might be driving such a large increase in health centers between 2021 and 2023?
Thank you in advance.
