group might correspond to just a few city blocks. Market Research Tools’ radius selection reports draw on block groups’ highly precise data.  Maps based on block groups (and the somewhat larger unit census tracts) are useful for decision-making because they are so specific.

Patty can use Market Research Tools to find exactly where concentrations of young people are clustered.  How?  First, she chooses some likely alternatives to consider – several street intersections she knows to be main arteries through residential areas. Going to Market Research Tools, she enters one of these alternatives for her "geography of interest" and chooses a radius of two miles around that intersection.

Next, Patty clicks "Go" to view a Demographic Profile report.  From the report screen she chooses the Thematic Map option and views a map showing the population count under age 20 for that geographic selection.  She prints the map and report.

Patty repeats this process for a second location, printing a new map and report.  She finds that both maps show roughly similar

over $100,000".  Now the map for one area shows a clear advantage over the other.

At the end of her session, Patty has the precise information she needs to make informed comparisons.  She is quickly able to find the part of town that contains the most affluent young people - her best potential customers.

Radius selections deliver the information you need to make decisions that are highly sensitive to geographic location.  Radius selections unleash the power of demographics.
