Objectives:
• To get familiar with Shapefile
• Learn how to manage and edit data in ArcGIS Pro
Data:
• Download the latest population data of all states (Table: B01003, ASC-1 Year Estimates) in the USA from Census data.census.gov/
• Download the latest TIGER Shapefile of all states in the USA from Census www.census.gov...

4. In Analysis/Tools, search and open the Join Filed tool. Join the table to the shapefile based on the common field.
5. Export data
5.1. Right-click the shapefile layer and select Data/Export Features to save the joined shapefile as a new shapefile to the project’s geodatabase.
5.2. Name the new file state_pop
5.3. Only keep the GEOID, NAME, and pop fields.
5.4. In the Environments, select the Output Coordinates as NAD_1927_Contiguous_USA_Albers
6. Remove the other layers and only keep the state_pop layer.
7. Field calculation
7.1. Add a new field, name it pop_dens, and data type double.
7.2. In the attribute table, select the pop_dens file, and right-click and choose Calculate field.
7.3. We want to calculate the population per square kilometer. Type (!pop! / !Shape_Area!)*1000000 in the formula.
8. Edit metadata

10.1. Select the state_pop layer and open the Feature Layer.
10.2. Click Symbology and choose graduated colors.
10.3. Change the field to pop_dens
11. Change map property
