# Maps for Visualizing Covid-19's Effect (Updated with comparisons)

Posted 4 years ago
 MODERATOR NOTE: coronavirus resources & updates: https://wolfr.am/coronavirus I added some more analysis here based on the suggestion of a friend. He asked about looking at what percentage of deaths were likely caused by covid-19. Thus, I took the average annual death rate per county, multiplied it by 7/365 to get average weekly death rate. I took this number and added the number of deaths from covid-19 over the last week to get an estimate of how many total people died. I then divided the number of covid-19 deaths by this number to get the rough percentage of people that died from the virus. As you can see below, there are some counties in which up to 75% of deaths were from covid-19. New York State (even outside of NYC) seems to have been hit the hardest. I had made some maps like this to look at crime statistics in the past but decided to adopt them to use The NY Times' covid-19 data. They turned out pretty nice so I thought I'd share them. The plots are all normalized by population since I would think healthcare capacity would scale roughly linearly with population. Excuse the crude hacks you'll find throughout. Update the local git repository with the NY Times data on GitHub. SetDirectory[NotebookDirectory[] <> "./covid-19-data"]; Run["!git pull -f"]; SetDirectory[NotebookDirectory[]];  Get a list of all the states in the continental United States. allStates = EntityList[EntityClass["AdministrativeDivision", "ContinentalUSStates"]];  Extract the boundary polygon(s) for each state. stateBoundaries = Map[{-#[[1]], #[[2]], -0.1} &, EntityValue[allStates, {"Polygon"}] /. {GeoPosition -> Identity, Quantity[x_, _] -> x}, {5}];  Get entities for the counties in each state. This takes an array of state names so we can narrow the analysis down to whatever set of states we'd like. counties[states_] := Flatten[Function[x, Join @@ EntityValue[{Entity[ "AdministrativeDivision", {x, "UnitedStates"}]}, EntityProperty["AdministrativeDivision", "Subdivisions"]]] /@ states]  Get the population, annual deaths, and FIPS code for each county in the list of states provided. properties[states_] := Flatten[(EntityValue[{counties[states]}, EntityProperty[ "AdministrativeDivision", #1]] &) /@ {"Population", "FIPSCode", "AnnualDeaths"}, 1]  Extract the strings of the county names from the entities. countynames[state_] := EntityValue[counties[state], "CanonicalName"]  Cut the full county names (e.g. "CentreCounty, Pennsylvania, UnitedStates") down to just the name of of the county (e.g. "Centre"). Cut the full state names down. stringLength[state_] := StringLength["County, " <> state <> ", UnitedStates"] countyShortNames[states_] := Flatten[Function[x, Table[StringDrop[ StringDrop[ToString[countynames[{x}][[i]]], -stringLength[x] - 1], 1], {i, 1, Length[counties[{x}]]}]] /@ states] allStateNames = EntityValue[allStates, "CanonicalName"]; allStateShortNames = Table[StringDrop[StringDrop[ToString[allStateNames[[i]]], -15], 1], {i, 1, Length[allStateNames]}];  Get the central location of each county and state so I can display tooltips if desired. loc[states_] := EntityValue[counties[states], "Position"] locStates := EntityValue[allStates, "Position"][[All, 1]]  Get the postal abbreviations for each state and make an array mapping short names to postal abbreviations. stateAbbreviations = (#1["StateAbbreviation"] &) /@ allStates; stateAbbreviationsShortNames = Transpose[{stateAbbreviations, allStateShortNames}];  Grab the data from the CDC stored in a local database and group by either state or county. I took the data from March and April of 2018 and calculated deaths per day. Needs["DatabaseLink"] conn = OpenSQLConnection[ JDBC["mysql", "localhost:3306/cdc"], "Username" -> "user", "Password" -> "password"]; statesFluPneuRaw = SQLExecute[conn, "SELECT State, Week, Influenza, Pneumonia, Total FROM \ State_flu_data WHERE Season like '2018-19'"]; \ heartDiseaseDeathsPerDayByCountyRaw = SQLExecute[conn, "SELECT County, County_code, sum(Deaths)/61 FROM \ Heart_disease_deaths_by_county WHERE Month_code like '2018/03' or \ Month_code like '2018/04' group by County"]; heartDiseaseDeathsPerDayByStateRaw = SQLExecute[conn, "SELECT substring(County,-2), Month_code, sum(Deaths)/61 FROM \ Heart_disease_deaths_by_county WHERE Month_code like '2018/03' or \ Month_code like '2018/04' group by SUBSTRING(County,-2)"]; cancerDeathsPerDayByCountyRaw = SQLExecute[conn, "SELECT County, County_code, sum(Deaths)/61 FROM \ Cancer_deaths_by_county WHERE Month_code like '2018/03' or Month_code \ like '2018/04' group by County"]; cancerDeathsPerDayByStateRaw = SQLExecute[conn, "SELECT substring(County,-2), Month_code, sum(Deaths)/61 FROM \ Cancer_deaths_by_county WHERE Month_code like '2018/03' or Month_code \ like '2018/04' group by SUBSTRING(County,-2)"]; circulatoryDeathsPerDayByCountyRaw = SQLExecute[conn, "SELECT County, County_code, sum(Deaths)/61 FROM \ Circulatory_deaths_by_county WHERE Month_code like '2018/03' or \ Month_code like '2018/04' group by County"]; circulatoryDeathsPerDayByStateRaw = SQLExecute[conn, "SELECT substring(County,-2), Month_code, sum(Deaths)/61 FROM \ Circulatory_deaths_by_county WHERE Month_code like '2018/03' or \ Month_code like '2018/04' group by SUBSTRING(County,-2)"]; respiratoryDeathsPerDayByCountyRaw = SQLExecute[conn, "SELECT County, County_code, sum(Deaths)/61 FROM \ Respiratory_deaths_by_county WHERE Month_code like '2018/03' or \ Month_code like '2018/04' group by County"]; respiratoryDeathsPerDayByStateRaw = SQLExecute[conn, "SELECT substring(County,-2), Month_code, sum(Deaths)/61 FROM \ Respiratory_deaths_by_county WHERE Month_code like '2018/03' or \ Month_code like '2018/04' group by SUBSTRING(County,-2)"];  Clean up the raw states influenza and pneumonia deaths for use here. statesFluPneuData = ({StringReplace[#1[[1]], " " -> ""], If[ToExpression[#1[[2]]] >= 40, ToExpression[#1[[2]]] - 39, ToExpression[#1[[2]]] + 52 - 39], ToExpression[#1[[3]]] + ToExpression[#1[[4]]], ToExpression[StringReplace[#1[[5]], "," -> ""]]} &) /@ statesFluPneuRaw;  Week 24 seemed to be the worst week for influenza and pneumonia deaths so I used that. Get rid of the data for Alaska, Hawaii, D.C., and NYC. worstFluPneuWeek = DeleteCases[Select[statesFluPneuData, #1[[2]] == 24 &], a_ /; MemberQ[{"Alaska", "Hawaii", "DistrictofColumbia", "NewYorkCity"}, a[[1]]]];  Clean up the raw cause of death data and removed Alaska, Hawaii, and D.C. Need to resort since the raw data is alphabetized by postal abbreviation. heartDiseaseDeathsPerDayStates = Sort[Function[ x, {Select[stateAbbreviationsShortNames, #1[[1]] == x[[1]] &][[1, 2]], x[[3]]}] /@ Select[heartDiseaseDeathsPerDayByStateRaw, #1[[1]] != "AK" && #1[[1]] != "HI" && #1[[1]] != "DC" &]]; respiratoryDeathsPerDayByState = Sort[Function[ x, {Select[stateAbbreviationsShortNames, #1[[1]] == x[[1]] &][[1, 2]], x[[3]]}] /@ Select[respiratoryDeathsPerDayByStateRaw, #1[[1]] != "AK" && #1[[1]] != "HI" && #1[[1]] != "DC" &]]; circulatoryDeathsPerDayByState = Sort[Function[ x, {Select[stateAbbreviationsShortNames, #1[[1]] == x[[1]] &][[1, 2]], x[[3]]}] /@ Select[circulatoryDeathsPerDayByStateRaw, #1[[1]] != "AK" && #1[[1]] != "HI" && #1[[1]] != "DC" &]]; cancerDeathsPerDayByState = Sort[Function[ x, {Select[stateAbbreviationsShortNames, #1[[1]] == x[[1]] &][[1, 2]], x[[3]]}] /@ Select[cancerDeathsPerDayByStateRaw, #1[[1]] != "AK" && #1[[1]] != "HI" && #1[[1]] != "DC" &]];  Extract the numerical values of the population, annual deaths, and FIPS code for each county in the list of states.

A couple other metropolitan areas have the data recorded en masse but I have not adjusted for those. rawData = Import[NotebookDirectory[] <> "./covid-19-data/us-counties.csv", "EmptyField" -> "0"]; nycData = Select[rawData, #1[[2]] == "New York City" &]; newData = DeleteCases[rawData, a_ /; a[[2]] == "New York City" || a[[2]] == "Bronx" || a[[2]] == "Kings" || a[[2]] == "Queens" || a[[2]] == "Richmond"]; Do[newData = Join[newData, (ReplacePart[#1, 4 -> fips] &) /@ nycData], {fips, {36005, 36061, 36047, 36081, 36085}}]  Import the raw data from "us-states.csv". rawStatesData = Import[NotebookDirectory[] <> "./covid-19-data/us-states.csv", "EmptyField" -> "0"];  This function takes a list of states and whether you want to extract "Infected" or "Dead" from the data, and normalizes it by the population of the county.

Show[(DateListPlot[#1] &) /@ normalizedData[{"Louisiana"}, "Dead"][[All, All, 1 ;; 2]], PlotRange -> All]  Since not all counties of the same number of days since the first infected/death I figure out when the first incident occurred for all the states in the list. I then pad the data with zeroes so that all counties have the same length of history.

Ultimately I simply normalized with 1000 infected per million people and 100 for dead per million, so this is really just a check to see if things are working correctly. {minCasesPerM, maxCasesPerM} = MinMax[historicalNormalizedDataStates[1, 1, "Infected"][[All, 3]]] {minCasesPerM, maxCasesPerM} = {0, 1000} {minCasesPerMStates, maxCasesPerMStates} = {0, 10000} {minCasesChangePerM, maxCasesChangePerM} = {0, 100} {423.025, 12296.9}  These functions takes a list of states (for the case using counties), the number of days ago to analyze and the data for infected or dead and generates all the information needed to make a 2D plot of counties in the state list colored by the rate of infected or dead.

The 'offset' parameter is used when I want to stack data. polygons3DStates[daysAgo_, offset_: 0, type_: "Infected"] := Apply[{ColorData["Rainbow"][2 #1], To3DComplex[#2, offset, 20 #1 + 10 #1]} &, Transpose[{paddedNormalizedDataStates[daysAgo, type][[ All, -daysAgo]][[All, 3]]/If[type == "Infected", 10000, 1000], polygonsStatesExpanded[[All, 1]]}], {1}]; Graphics3D[polygons3DStates[6, 0, "Dead"], ImageSize -> 2000, Boxed -> True, Axes -> False, BoxRatios -> Automatic]  Created the extruded states with the height proportional to the normalized influenza/pneumonia data. polygons3DStatesFluPneu[daysAgo_, offset_: 0, type_: "Infected"] := Apply[{ColorData["Rainbow"][200 #1], To3DComplex[#2, offset, 200 #1]} &, Transpose[{paddedNormalizedDataStates[daysAgo, type][[All, -daysAgo]][[All, 5]]/If[type == "Infected", 10000, 1000], polygonsStates[[All, 1]]}], {1}]; Graphics3D[polygons3DStatesFluPneu[6, 0, "Dead"], ImageSize -> 2000, Boxed -> True, Axes -> False, BoxRatios -> Automatic]  Created the extruded states with the height comparing the normalized C-19 data over the last seven days with various other death estimates. polygons3DStatesLastWeek[comparison_, offset_: 0, padLength_: All, type_ : "Infected"] := Module[{x}, x = ({#1[[All, 5]][[1]], #1[[All, 3]][[-1]] - #1[[All, 3]][[1]]} &) /@ paddedNormalizedDataStates[7, type]; Apply[{Opacity[1], Yellow, To3DComplex[#3, 0, 50 (#2)], Opacity[0.8], ColorData["Rainbow"][5 #1], To3DComplex[#3, 50 #2, 50 (#1 + #2)]} &, Transpose[{x[[All, 2]]/If[type == "Infected", 10000, 500], ( 7 paddedNormalizedDataStates[padLength, type][[All, -1]][[All, comparison]])/If[type == "Infected", 10000, 500], polygonsStatesExpanded[[All, 1]]}], {1}]] ` A graphic showing the deaths from C-19 per capita over the last week on top of the estimated deaths from heart disease over the same time period. As you can see, over the last week of data, covid-19 is the leading cause of death in many states.
