Description: This data shows the population change over the latest 7 days when Population Density data from Meta are available. The change is calculated using a linear regression over the daily data showing population change from 1600 to 2359 hrs UTC.
Hotspots, or areas of interest, are visualized using the following color levels:
- Decreasing of population density change are shown in brown, which signify a small but consistent decrease in population density in these regions. Three shades of brown indicates statistical significance from the linear regression applied to detect the trend over time (p < 0.1, p < 0.05, p < 0.01).
- Increasing levels of population density changes are shown in cyan, which indicates a small but consistent increase in population densities in these regions. Three shades of cyan indicates statistical significance from the linear regression applied to detect the trend over time (p < 0.1, p < 0.05, p < 0.01).
This analysis of population density changes uses anonymized and aggregated Meta (Facebook) data can indicate that people are leaving or coming-into a specific location at the time period of the analysis. This is not necessarily indicative of specific forced displacement, but likely one of the following scenarios from our remote analyses:
- Seasonal changes
- Fluctuations in the general population
- Changes in population, which may be related to displaced people from Ukraine
