Mobility data analysis for Virginia

The data is from SafeGraph and is based on cell phone data. This data can be analyzed to show how many individuals visit different points of interest at any given time. This tool uses the total number of visits to particular categories to drive transmissions. The following analysis characterizes the total visits to 5 different categories of locations over 2019 and 2020 to provide context for the use of this tool.

This tool includes three metro areas

These areas align with various census-designated metropolitan statistical areas (MSAs). In the following analyses, these area names have been abbreviated for clarity:

• Washington DC Metro: Washington DC MSA, which includes Arlington, Alexandria, and several counties stretching from Maryland to West Virginia
• Richmond Metro: The Richmond, VA MSA which includes the city of Richmond and surrounding counties
• Eastern VA: The Eastern VA MSA which includes Virginia Beach, Norfolk, and Newport News, and surrounding counties

2019 Mobility

Total foot traffic for the 3 regions across the 5 categories over the course of 2019

2020-21 Mobility

Total foot traffic for the 3 regions across the 5 categories over the course of 2020 and 2021.

Comparison of 2020-21 vs. 2019-2020

Calculate the proportion of Foot Traffic in 2020-21 with respect to 2019-20:

Proportion = Foot Traffic in 2020 / Foot Traffic in 2019

Some Categories had more traffic in 2020 than in 2019 and thus will be over 1.
Weeks in 2021 are compared to the prepandemic weeks of 2020 for continuity.

Most recent proportions

Current mobility is set at the most recent week values

Tables of proportions 2020-21 vs. 2019-20

Data table comparing the number of visits between 2019-2020 pre-pandemic time to 2020-2021 post pandemic time. The proportion of visits (2020-2021 / 2019-2020) are shown across the MSAs and POI categories.
Thus values above 1.0 mean there are more visits during that week in 2020-2021 than in the same week in 2020-2021
