Note: This project was changed in mid-semester, in response to the COVID-19 outbreak. The old project was “Improved Generalization of Pelvis Landmark Detection”, and its web page can be found here.
At present, this page is based on the original paper, available here.
As the coronavirus disease 2019 (COVID-19) becomes a global pandemic, policy makers must enact interventions to stop its spread. Data driven approaches might supply information to support the implementation of mitigation and suppression strategies. To facilitate research in this direction, we present a machine-readable dataset that aggregates relevant data from governmental, journalistic, and academic sources on the county level. In addition to county-level time-series data from the JHU CSSE COVID-19 Dashboard [1], our dataset contains more than 300 variables that summarize population estimates, demographics, ethnicity, housing, education, employment and income, climate, transit scores, and healthcare system-related metrics. Furthermore, we present aggregated out-of-home activity information for various points of interest for each county, including grocery stores and hospitals, summarizing data from SafeGraph [2]. By collecting these data, as well as providing tools to read them, we hope to aid researchers investigating how the disease spreads and which communities are best able to accommodate stay-at-home mitigation efforts.
COVID-19 has had a devastating impact on the United States’ health care system, economy, and social wellbeing. Despite early promises of an ”American Resurrection” by April 12, 2020 [4], social distancing measures remain in effect through the month of April, and many scientists and public health experts speculate they may last much longer. As of the time of writing, restrictions in Hubei province, China, where the disease originated in December, 2019, are only now gradually being lifted [5]. Confirmed COVID-19 cases, hospitalizations, and—unfortunately—deaths are increasing exponentially. Drastic interventions like social distancing are necessary to slow the spread of the disease, giving more time to
* provide treatment within our healthcare system’s capacity, * develop effective testing capability, * establish sophisticated tracing mechanisms, and * discover novel treatments for the virus.
At the same time, the current mitigation strategies have had severe effects on society and the economy. Widespread closures of schools and daycares have left working parents with limited childcare options [6]; shuttered bars, restaurants, and entertainment venues have forced owners to lay off employees, predominantly in the service industry [7]; and a plummeting stock market has fueled fears of a recession which may far outlast the current crisis [8]. To combat these effects, representatives recently passed the largest economic stimulus package in U.S. history [9]. However, no stimulus can offset the effects of an indefinite quarantine. Determining when and how to roll back non-pharmaceutical interventions in a manner which is safe and responsible is of the utmost importance.
The initial quarantine period is necessary to avoid overwhelming our hospital systems. After this, we must balance reducing the risk of spread with the adverse economic consequences of millions of furloughed and unemployed people. To inform this process, we have curated a machine-readable dataset that aggregates data from governmental, journalistic, and academic sources on the county level. While most of these sources are freely available, there is significant work to align them and put them in a standard format that enables analysis. In addition to time-series data from [1], which details COVID19 per-county infections and deaths, our dataset contains more than 300 variables that summarize population estimates, demographics, ethnicity, housing, education, employment and income, climate, transit scores, and healthcare system-related metrics. Further, we source a significant number of journal articles detailing implementation dates of interventions, including stay-at-home orders, school closures, and restaurant and entertainment venue closures [10]–[48]. Finally, we aggregate out-of-home activity data from [2] in each county, possibly measuring compliance with the aforementioned restrictions. We hope that this dataset proves to be a useful resource to the community, facilitating important research on epidemiological forecasting. In particular, a machine learning approach to identify highly relevant factors may inform a graduated rollback of isolation measures and travel restrictions.
Thus far, this work has focused on the aggregation and visualization of a county-level dataset containing static and dynamic data related to epidemiological modeling. Going forward, I am involved in efforts to predict how rolling back interventions will affect a possibly flattening curve, using clusters of counties to extrapolate previous spread.

We describe the structure of our dataset, which includes each component in its raw form as well as a narroweddown, machine-readable form conducive to a machine-learning approach. Table I summarizes the sources and availability for each type of data, and a full description of each variable can be found in our repository.
We populate a CSV file with 348 variables for 3220 county-equivalent areas (as well as the fifty states, District of Columbia, and the whole United States) with numerous types of data, including population, education, economic, climate, housing, health care capacity, public transit, and crime statistics. Each area is uniquely identified by its Federal Information Processing Standard (FIPS) code, a five digit number where they first two digits designate the state, and the last three digits describe the county-equivalent. Our sources include the United States Census Bureau [49], [50], [55], [56], the United States Department of Agriculture (USDA) Economic Research Service [51], [52], the National Oceanic and Atmosphere Administration (NOAA) [53], the Association of American Medical Colleges (AAMC) [57], the Henry J. Kaiser Family Foundation (KFF) [3], [58], [59], the Center for Neighborhood Technology (CNT) [61], and the Bureau of Justice Statistics, Department of Justice (DOJ) [62]. Perhaps most relevant to the ongoing effort to mitigate the effects of COVID-19 in the U.S. is county-level healthcare system capacity. The dataset includes detailed counts for each type of medical practitioner as well as the number of Intensive Care Unit beds in each county.
For the most part, these basic descriptive variables are unaltered from their original state. Where appropriate, missing values have been imputed with the state-wide average. See original paper.
Our dataset describes mitigation efforts taken at the state level, including stay-at-home advisories, banning large gatherings, public school closures, and restaurant and entertainment venue closures. For machine readability, we provide each date of implementation as a Gregorian ordinal, i.e. the integer number of days starting at January 1, Year 1 CE, consistent with standard software libraries. Moreover, these data are provided according to the same county-level row ordering as our county descriptor data (see Sec. III-A). Interventions made at the state level have been assigned to each county in that state, and we include county-level interventions wherever possible An intervention is designated NA if the county or state has not yet enacted it.
We have aggregated point-of-interest location data gathered from user’s smartphones to show out-of-home activity, using raw data from [2]. For privacy and IP reasons, our dataset does not include user location data in its raw form but rather in several time-series files summarizing county-level activity. Fig. 1 shows the time-series for selected counties which have a high incidence of COVID-19 cases. The decline in overall activity on May 12 corresponds to an increased media attention and stay-at-home advisories in those areas. At the same time, a spike in grocery store visits points to a panic-buying spree which has since subsided.
Finally, we provide time-series data for the cumulative number of COVID-19 confirmed cases and related deaths, from [1]. This data begins on January 22, 2020. It should be noted that epidemiological modeling efforts may want to consider the uncertainty surrounding U.S. testing [71], on which these data are based. At the time of this writing, efforts to improve the availability of COVID-19 tests are ongoing, but the current strategies prioritize patients with severe symptoms. Thus, modeling efforts may wish to take into account random subsampling of the true population, where untested individuals still spread the virus. This is especially true given that nearly half of all COVID-19 infections may be asymptomatic [72]. Fig. 3 shows the infections in King County, WA collected by [1]. King County had an early confirmed cases of the virus, and the exponential curve illustrates the rapid growth currently taking place there as a result.
