Step 1: Assign people to geographic areas and drop small counts We assign people to geographic areas based on their typical nighttime location and omit areas where few people live.

Step 2: Calculate movement distribution We quantify how much people move around by selecting a random location update for each person during the day, and determining how far away that is from their typical nighttime location.

Step 3: Assign Distance Categories We calculate the percentage of people in each of four distance categories based on how far they travel from home on a given day, including 0km, 0-10km, 10-100km and 100km+.

Step 4: Add noise We calculate an appropriate amount of noise to add to the total tiles visited for each region to ensure it is effectively impossible to re-identify any individual.
