Hurricane Ian: Central and Eastern Florida, United States

28 September, 2022; 1600

Wednesday, September 28, 2022

Hurricane Ian passed over the Central and Eastern regions of Florida on Thursday, September 29 at Category 1 strength. Power outages were not prevalent throughout this region, with only modest outages reported in Volusia, Brevard, and Orange counties.

Most areas showed population increases, due in part to evacuations ordered in Southwestern Florida, which bore the brunt of the storm. Coastal areas, including Daytona Beach and Cocoa Beach, showed modest declines between 1% and 9%. Areas from Kissimmee to Alafaya showed increases in population between 7% and 10%.

Volusia and Brevard counties have a high percentage of elderly residents at 24%, with over 13,000 users of power-dependent medical devices between the two counties. Orange county has a younger population compared to the other nearby, with only 12% of residents over the age of 65. Given its relatively higher total population, it has roughly the same average number of power-dependent medical device users as Volusia and Brevard.


Hurricane Ian: Charlotte and Lee Counties, Florida, United States

28 September, 2022; 1600

As Hurricane Ian made landfall near the counties of Charlotte and Lee, widespread reductions in population density could be detected throughout the area.

Charlotte and Lee saw population reductions between 65% and 74%. These reductions took place a day before the hurricane made landfall. Using the Facebook data alone as a signal, we can detect more than 100,00 people remaining in the heavily-flooded coastal counties of Charlotte, Lee, Sarasota, and DeSoto.

On September 28, no town or municipality registered increasing population densities. On the low end, areas such as Sebring and Lakewood Ranch showed declines between 1% and 22%. On the high end, areas such as Cape Coral and Port Charlotte showed declines of 74% or more.

Severe power outages took place in Manatee, Collier, Lee, and Sarasota counties, affecting 100% of customers. Cumulatively, those counties contain nearly 17,000 people registered as using power dependent medical devices.


Hurricane Ian: West Coast Florida, United States

27 September, 2022

This report summarizes vulnerability and population mobility data for the regions south of Tampa Bay, Florida. Charlotte, Sarasota, Lee, and DeSoto Counties are predicted to be where Hurricane Ian will first make landfall late Wednesday, September 28, or early Thursday, September 29.

Interpretation: The population, particularly in Charlotte County, tends to be disproportionately older than other counties in the area. However, Sarasota County has a higher proportion of patients with power-dependent medical devices.

Although relatively significant decreasing movement trends can be detected, especially in smaller coastal communities, some areas are showing increasing population trends over the 26th and 17th. A number of places in Charlotte County in particular are still showing a large number of people who have not evacuated.


Catastrophic Flooding in Pakistan

13 September, 2022

Summary: The updated maps below shed light on the evolving displacement patterns as floods continue to devastate Pakistan. A new data layer has been added in the maps below to show the population change at administrative level 2, as the tile level population update has recently encountered issues.

Interpretation: Most areas, especially the populous cities in the Northeast part of Pakistan, have returned to pre-crisis levels. The flooded zones of the south still experience significant decreases in population densities. Population mobility trends show heavy movement out of areas surrounding Hyderabad and Karachi, and into more northern cities like Lahore, Multan, and Quetta.


05 September, 2022

Summary: The interactive map below shows population movement patterns driven by recent floods in Pakistan between August 13, 2022 and September 5, 2022. Data reflecting population movement originated from selected level 2 administrative units of Pakistan, including Karachi, Larkana, Malakand, Quetta, and Sukkur.

Data Sources: Population maps were generated using data provided by Data for Good at Meta. For more information about the disaster population maps provided by Data for Good at Meta, please refer to this link.

Data on flood extent is gathered using the Visible Infrared Imaging Radiometer Suite (VIIRS), an instrument that collects visible and infrared images and global observations of the land, atmosphere, cryosphere, and oceans.

Interpretation: The red arrows on the map show the directional patterns of population movement. The size (width) of the arrows correlates with the the volume of individuals displaced from the selected origins. The larger the arrow, the greater number of movement vectors. Transparency of arrows indicates the baseline population traveling between the origin and the destination under the pre-crisis situation.


30 August, 2022

Summary: The following data maps show population density changes between August 13 and August 30, 2022 in areas affected by floods in Pakistan.

Data Sources: These data show population changes compared to pre-crisis baseline in Pakistan on a daily basis for all level 3 administrative units of Pakistan. The data is time-enabled to show the change from August 13, 2022 to the latest date when population change data harvested by Data for Good at Meta is available. Population maps provided by Data for Good at Meta are generated based on users of Facebook.

Interpretation

  • Decreases in population density changes are reflected by brown dots.
  • Increases in population density changes are reflected by green dots.
  • Similarly to previous maps, the saturation and transparency of the colored dots reflect the strength of changes in population densities. The transparency of the dots also reflects the confidence in data representativeness.
  • Higher saturation = greater rate of change.
  • Lower saturation = lower rate of change. 
  • Low transparency/high saturation higher confidence in data representativeness. 
  • High transparency/low saturation = lower confidence in data representativeness
