As of 2007, Texas had the largest concentration of colonia residents in the U.S., with approximately 400,000 living in over 2,000 colonias. New Mexico had the second largest, followed by Arizona and California. However, as remote location and stealthy development characterize many colonias, exact counts are difficult and figures can quickly change. Despite the high count of individuals living in these areas, the severity of the living standards in colonias has yet to become common knowledge for U.S. citizens. Scholars have found that little has been done to remedy the living standards of the colonians, as their situation has become normalized by the public and associated with the "lawlessness" of the Mexico–U.S. border region. Scholars have criticized the naming of these settlements as "colonias", stating that the use of the Spanish word not only creates difficulties within the public policy sector of government, but also fosters the notion that these settlements are alien and not a part of the U.S. However, those within the public that do recognize colonias and their living conditions view them as "border slums", while scholars have since the 1990s described them as a "third world" within the United States. While poor living standards do persist in these areas, a positive side does exist for colonias and is often disregarded by media and policymakers. For the border region's poor, colonias provide affordable housing and the opportunity to obtain the American Dream of owning a home. Some scholars have praised colonians for seeking the realization of this dream through self-help. Because of this, the informed public has begun urging policymakers to make decisions that will not eliminate colonias but instead both enhance the living conditions and promote the incremental approach as a housing strategy, stating that this informal housing option creates opportunity.
