Population During Crisis Analysis#
The Population During Crisis dataset tracks the number of Facebook users in different geographic regions, spanning August 25th, 2024, to September 5th, 2024. This dataset provides insights into:
The count of Facebook users and how this number changes over time.
Identifying areas heavily impacted by the crisis.
Understanding population movement dynamics and estimating how many people are affected.
Purpose#
This analysis examines how population counts fluctuate at the national level in Bangladesh during and after the recent political crisis.
Objectives#
National Trends#
Track the total number of Facebook users in Bangladesh across different time intervals (
00:00,08:00,16:00).Compare the crisis period with the baseline period to understand movement patterns.
How is the Population Calculated?#
The dataset has two main variables baseline population and crisis population
The baseline population (n_baseline) is derived from pre-crisis Facebook population maps, using the following methodology:
Facebook counts users with location services enabled on their mobile devices.
The dataset captures the most frequent location of users in 8-hour intervals.
If a user appears in multiple locations within the same interval, only their most frequent location is counted.
Privacy-preserving techniques ensure that individual movements cannot be identified.
The crisis population (n_crisis) represents the actual number of Facebook users observed during the crisis period under the same methodology.
