Social Capital: The degree to which a community or society collaborates and cooperates
(through such mechanisms as networks, shared trust, norms and values) to achieve mutual
benefits. There are many definitions and discussions about social capital, for more information
see Robert D. Putnam's Bowling Alone: The Collapse and Revival of American Community
(Simon & Schusterk Publishing, 2000).
Trans-Border Residents: For the purposes of this study, trans-border residents are defined
as individuals of U.S. or Mexican citizenship or residency that live in either San Diego or Baja
California and that cross the international border to work, attend school, shop or visit friends
and family on a regular and periodic basis. (See page 9 for a detailed description).
Transboundary Impact: A health, environmental or socio-economic impact that has crossborder
consequences across international or political boundaries. While some transboundary
impacts are regional, as in San Diego-Tijuana, others can be more far reaching as is the
case with the destruction or disruption of critical habitats for migratory bird species that come
from to this region from as far away as Canada.
Transnational Residents: Immigrants/migrants in the United States with sustained two-way
contacts and links to friends, family and relatives in their place of origin. (See page 12 for a
detailed description).
