Movements between city tiles

Pick a city - either Nairobi or Mombasa in Kenya or Lagos or Abuja in Nigeria to the right →

Similar to the visualisation of ´Movement between municipalities´ we can visualize the distribution where people spend their days relative to their nights. This visualisation is made to explore the movement patterns over time within a city.

This visualisation also based on the three daily time windows and movement of people are calculated exactly the same like the Movement Maps except that is it done between tiles instead of municipalities. For a detailed explanation of the movements are calculated see Movements between municipalities.

The map below displays the day-to-day between-tile travel patterns in a city. By default the map displays Change, which is the percentage deviation between the size of the working population on the date selected with the slider, and the corresponding baseline (before lockdown). Clicking On date shows value for the date selected in the slider and Baseline for the corresponding baseline day. You can click any tile to reveal where people who live there go to work.

In this map, only movement within the same city in regarded, meaning movement in and out of the city is not included. A general trend of the two Nigerian cities, is that we see that the deviation (change between Baseline and On date) decrease over time, similar to what is observed in the ´Movement between municipalities´. This percent change is ‘very’ negative from the start of the period until around end of April, where the travel patterns within in the city seems to start returning to the baseline.

This figure is interactive! You can:

• Hover the curser over an tile to display the share of the Facebook population that makes daily journeys we assume represents work.
• Click any tile to see where the population in that tile goes to work.
• Drag the time slider to display data for different dates.
• Select either to display valus for the selected date (On date), the Baseline or the percentage deviation between these (Change).
• Hold shift key after having selected (clicked) a tile to display where people who work there live (as opposed to the default: where people who live there work).
• Press the escape key to unselect a tile.
