Using a statistical overlay

Statistical Overlay transfers the selected attributes from one layer to another. One layer, called the Primary Input, receives the attributes from another layer, called the Secondary Input.

There are two possible results when you transfer attributes between the layers:

Each shape in the Primary Input can receive the attributes from one shape in the Secondary Input. For example, you can transfer the county attributes from a county layer to a cities layer. Each city in the Primary Input receives the attributes from the county that contains the city.
Each shape in the Primary Input can receive the attributes from many shapes in the Secondary Input. You must specify a function to aggregate the attributes from the Secondary Input. For example, you can transfer the city attributes from a cities layer to a county layer. Each county in the Primary Input receives the sum of the population of the cities contained within that county.

From the Analysis menu, click Overlay.
In the Overlay Wizard, enable the Statistical option and click Next.
In the Primary Input area, choose a file from the File list box. If a file is not listed, click Browse, locate and select a file from the File Selector window, and click Open.
Choose a layer that will receive the attributes from the Layer list box. If you want to include only the selected records in the layer, enable the Use selected shapes only check box.
In the Secondary Input area, choose a file from the File list box.
Choose a layer that contains the attributes you want to add to the Primary Input layer from the Layer list box. If you want to include only the selected records in the layer, enable the Use selected shapes only check box.
Click Next.
Click Finish.

You can add function fields to the output Attribute Manager. (See Adding function fields to output layers)

You can also add fields containing other attributes.
