Your home address may be used to access public information about the area where you live. This is to help researchers learn about how your neighborhood encourages physical activity. The results from this study will only be reported as a group and you will not be identifiable from any products resulting from this study (such as research papers). Your home address will never be released or published in any form. Your address will be stored separately from other study data, and only the study chair will be able to see the data after the neighborhood information has been collected.
