Creating a tool parameter with a drop-down selection

Is it possible to have a tool parameter be a drop-down selection?  For example, let's say I want to analyze populations of different ethnicities in different states.  I have one drop-down selection for the ethnicity and another for the state.  I know Python could probably make this work but not sure if ArcGIS has the ability to establish parameters this way.

Any help on this topic is greatly appreciated!  Thanks!
