In recent years, it has become clear that there exists a ''de facto'' union with neighbouring city San Cristóbal de La Laguna (141,627 inhabitants as in 2005 census) due to the rapid population growth and reduction in undeveloped space between the cities, as their suburbs merged, forming a metropolitan area with 420,198 inhabitants (including the nearby municipalities of Tegueste, Candelaria and El Rosario). Regarding this situation, the mayor of Santa Cruz, Miguel Zerolo Aguilar and his La Laguna counterpart, Ana María Oramas Moro, both belonging to the Canarian Coalition, stated several times to local media that they shared a willingness to proceed to a full political union between their municipalities, even though the decision was postponed to a date after the local elections in 2007. As of 2012 the merger is no longer part of the political agenda.
