Lancaster Area Change in Mobility
What Do These Graph Show?
As you are probably aware, public health experts have been urging people to practice social distancing in order to “flatten the curve,” or in other words to slow the growth of transmission of the virus. While this may not reduce the total number of people who become infected, it does mean fewer people will become infected at one time. This is incredibly important because we do not want to overwhelm the healthcare system and use up limited resources such as ICU beds and ventilators all at once.
Location analysis companies such as Cuebiq are tracking approximately 15 million cellphone users in the U.S. and reporting on changes in median distance traveled by people in different areas nationwide from this cellphone data. We have plotted this mobility data for the Lancaster area over time, so you can see how well people have been practicing social distancing and limiting their movement. Then we show how the Lancaster area compares to other major metro areas in the United States in terms of social distancing. Also shown is a similar graph produced by a company called Descartes that has a similar measure, but that focuses only on the longest trip taken per day.
