Examples

Basic Examples (2) 

Retrieve the data:

In[1]:=
ResourceData[\!\(\* TagBox["\"\<Census Tract Entity Store\>\"", #& , BoxID -> "ResourceTag-Census Tract Entity Store-Input", AutoDelete->True]\)]
Out[1]=

Register the EntityStore:

In[2]:=
EntityRegister[ResourceData[\!\(\* TagBox["\"\<Census Tract Entity Store\>\"", #& , BoxID -> "ResourceTag-Census Tract Entity Store-Input", AutoDelete->True]\)]]
Out[2]=

Scope & Additional Elements (3) 

Show census tracts in Cook County, IL:

In[3]:=
GeoGraphics[{EdgeForm[Black], Polygon@EntityClass["CensusTract", "ADM2" -> Entity["AdministrativeDivision", {"CookCounty", "Illinois", "UnitedStates"}]]}]
Out[3]=

Find property classes matching a particular topic:

In[4]:=
Select[EntityValue["CensusTract", "PropertyClasses"], StringContainsQ[CommonName[#], "educational attainment"] &][[;; 5]]
Out[4]=

List all properties in a property class:

In[5]:=
EntityProperties[EntityPropertyClass["CensusTract", "B17003"]][[;; 5]]
Out[5]=

Visualizations (3) 

Generate a heat map of median household income in Cook County census tracts:

In[6]:=
GeoRegionValuePlot[ EntityValue[ EntityClass["CensusTract", "ADM2" -> Entity["AdministrativeDivision", {"CookCounty", "Illinois", "UnitedStates"}]], EntityProperty["CensusTract", "B19013_001E"], "Association"]]
Out[6]=

Generate a plot of population by race in a given US county’s census tracts (each point represents one person in a given race category, with points randomly distributed within each tract polygon):

In[7]:=
RacePointMap[usCounty_] := Block[{rawdata, randompoints, cols, leg}, rawdata = EntityValue[ EntityClass["CensusTract", "ADM2" -> usCounty], { EntityProperty["CensusTract", "C02003_003E"], EntityProperty["CensusTract", "C02003_004E"], EntityProperty["CensusTract", "C02003_006E"], EntityProperty["CensusTract", "C02003_005E"], EntityProperty["CensusTract", "C02003_007E"], EntityProperty["CensusTract", "C02003_008E"], EntityProperty["CensusTract", "C02003_009E"], "Polygon"}]; Quiet[ randompoints = Cases[rawdata, Pattern[x, Blank[]] :> { RandomGeoPosition[ Part[x, -1], Part[x, 1]], RandomGeoPosition[ Part[x, -1], Part[x, 2]], RandomGeoPosition[ Part[x, -1], Part[x, 3]], RandomGeoPosition[ Part[x, -1], Total[ Part[x, Span[4, 6]]]], RandomGeoPosition[ Part[x, -1], Part[x, 7]]}]; Null]; cols = { RGBColor[0.621866, 0.909026, 0.965408], RGBColor[0.909499, 0.582605, 0.44213], RGBColor[1, 1, 0.4], RGBColor[0.797253, 0.904982, 0.410498], RGBColor[0.645075, 0.644968, 0.978851]}; Quiet[ Legended[ GeoGraphics[{ Map[{ Opacity[0.25], PointSize[Small], Part[cols, 1], Point[ Part[#, 1]], Part[cols, 2], Point[ Part[#, 2]], Part[cols, 3], Point[ Part[#, 3]], Part[cols, 4], Point[ Part[#, 4]], Part[cols, 5], Point[ Part[#, 5]]}& , randompoints]}, GeoBackground -> "StreetMapNoLabels", ImageSize -> Full], SwatchLegend[ cols, {"white", "black", "Asian", "other single race", "two or more races"}]]]]
In[8]:=
RacePointMap[ Entity["AdministrativeDivision", {"AlleghenyCounty", "Pennsylvania", "UnitedStates"}]]
Out[8]=

Compare earnings for men and women in a single Census tract:

In[9]:=
CensusTractIncomeChart[ct_Entity] := Block[{male, female, bins, m, f}, male = Rest[ Sort[ Select[ EntityProperties[ EntityPropertyClass["CensusTract", "B20001"]], StringContainsQ[ CommonName[#], " male"]& ]]]; female = Rest[ Sort[ Select[ EntityProperties[ EntityPropertyClass["CensusTract", "B20001"]], StringContainsQ[ CommonName[#], "female"]& ]]]; bins = StringTrim[ Part[ StringSplit[ CommonName[male], " | "], All, 4], "]"]; m = EntityValue[ ct, male]; f = EntityValue[ct, female]; Row[{ PairedBarChart[ m, f, BarSpacing -> {Automatic, Automatic, 0.1}, PlotLabel -> Column[{ "Sex by earnings for the population 16+ years", CommonName[ct]}], ChartLabels -> {{"male", "female"}, Automatic, bins}, ChartStyle -> {{LightBlue, LightOrange}, None, None}, ImageSize -> 400], GeoGraphics[{ EdgeForm[Black], Red, Polygon[ct]}, ImageSize -> {Automatic, 400}, GeoRangePadding -> Quantity[2, "Miles"]]}]]
In[10]:=
CensusTractIncomeChart[RandomEntity["CensusTract"]]
Out[10]=
