We will contact everyone in our database of LAAs by regular mail, e-mail, and phone in May 4, 2015 in order to ensure that all LAAs are given the chance to participate in this important research study. LAAs will access the Census through this web page. We will provide both a paper version of the questionnaire and a secure web-based Census form. Each LAA will be assigned a unique Survey Key that will provide access to the web-based form. If you have any questions or concerns, please feel free to contact Graciela Kahn, Research Coordinator, at [email protected] or give us a call at 202.371.2830.
