# US map using counties data

## Creating US map using US Counties data

US Counties can be used to build a US Map with any custom grouping of Counties using VitaraMap tools.

## Vitara County grouping tool <a href="#vitara-county-grouping-tool" id="vitara-county-grouping-tool"></a>

County grouping is done using the same tool used for ZipCode grouping.

Click on the link to access the tool:

[VitaraMaps - Tool for merging counties](https://cloud.vitaracharts.com/maptools/zipcode.html)

The below is screenshot of the tool.

### **Steps 1:**

After navigating to the webpage select the “US County Map” as shown in the image above.

### **Step 2:**

To arrange counties based on column data, select a “Data” file (csv format) with at least two columns of data.

### **Step 3:**

Fill “Group By” and “Apply Grouping To” fields to merge and export.

## Example of County’s aggregation: <a href="#example-of-countys-aggregation" id="example-of-countys-aggregation"></a>

The sample below shows counties organized into states (approximate data for county and state categorization is utilized).

FIPS indicates the county code and related states in the image below.
