    Synthetic Populations

      Synthetic populations for regions of the World (SPW) is a collection of data sets, each data set being a synthetic population for a country, or state, both of which will be referred to as a region in the following. At a high level, a synthetic population of a region as provided here captures the people of the region with selected demographic attributes, their organization into households, their assigned activities for a day, the locations where the activities take place, and thus where interactions among population members happen (e.g., spread of epidemics).  

    The methodologies used to create these datasets were also used to generate two synthetic population datasets for the UK-US Privacy-Enhancing Technology challenge. The challenge is focused on accelerating the adoption and development of privacy-enhancing technologies (PETs): Transforming financial crime prevention and boosting pandemic response capabilities through privacy-preserving federated learning.

    Our team has generated the two synthetic population datasets provided in the Pandemic Response Challenge. The first covers the population of the UK, and the second the population of the state of Virginia, USA. We used an outbreak simulation that created 63 days-worth of data, subsequently split into 56 days of training data and 7 days of test data.

     

    Global PatchSim Dataset

    PatchFlow is a set of pre-calculated networks for simulating the meta-population SEIR model at a global level. For the current version, using openly available datasets on population sizes [1] at the resolution of administrative regions (admin2 and admin3) [2] and age mixing matrices [3], we construct country-specific mobility networks based on a radiational model [4,5]. These networks are constructed to be compatible with the open-source meta-population simulation engine, PatchSim [6]. For more information, see below (in Tools).

    This project is supported by the National Science Foundation under the NSF RAPID: COVID-19 Response Support: Building Synthetic Multi-scale Networks (PI: Madhav Marathe, Co-PIs: Henning Mortveit, Srinivasan Venkatramanan; Fund Number: OAC-2027541).

     
     

    Virginia County-level NPIs

     

    The team at Network Systems Science and Advanced Computing (NSSAC) Division of the Biocomplexity Institute and Initiative (BII) at the University of Virginia gathered data on non-pharmaceutical interventions (NPIs) against COVID-19 from counties and independent cities in Virginia. NPIs are methods for reducing the spread of a disease that do not involve vaccines or drug treatments. Specifically, we look for dates when closures or mandates were implemented or lifted in the following five categories: masks, businesses, pre-K-12 schools, colleges, and religious organizations.

    Baidu Mobility Data for January - April 2020

     

    This archive contains mobility data made public by Baidu and scraped from their qiangxi.baidu.com website in February and March 2020. We have reformatted the data into a more easily computable form, comma-separated value (.csv) files providing the full origin-destination matrix for each day. We are publishing this reformatted version for research purposes under Article 22 of the Copyright Law of the People’s Republic of China. We make no representation as to the suitability of the data for any purpose but nevertheless hope that it may be useful for researchers trying to calibrate models of 2019-nCov.

    We wish to thank Baidu especially for making these valuable data available and encourage them to continue to do so. Thanks also to Chunhong Mao for making us aware of this data source and explaining what the data represent and to James Schlitt for scraping the data.

      PatchSim

       

      We have developed a national-scale metapopulation model for the spread of influenza by integrating both local and long-distance mobility data. For the example below, we combined data on commuter mobility from the American Community Survey (ACS) with domestic airline passenger data from the Bureau of Transportation Statistics (BTS) to capture human mobility across the country. Next, we adopted a metapopulation approach to simulate epidemic spread at the spatial resolution of counties (patches) wherein the temporal travel matrix is used to represent the flow of people between these patches: PatchSim.

       

      PatchSim can be used in modeling a variety of situations. Click the links below to learn about:

      Building on our long-standing work on synthesizing social networks, we will develop new methods for estimating MSML networks. This estimation will operate on diverse global data sets; the team has developed strong relationships with multiple vendors to acquire novel data sets to achieve this goal. We will create open-source synthetic data sets, applications, and tools.

      Additionally, we have developed methods for using traditional administrative data sets — our initial research has led to global synthetic contact networks. This research will be extended using new sources of anonymized mobility data, electronic health records, and smart-device data, as well as real-time data pertaining to individual and community level awareness and behavioral changes. Some of these signals are voluminous, and parsing them through crowdsourcing would be expensive and time-consuming; carefully choosing a subset of the signals that can be parsed intelligently by the “crowd” is a novel stochastic optimization problem that generalizes standard PAC (probably approximately correct) approaches. Validation of such MSML networks is a challenge, which will be addressed by extending our earlier work.
