However, the 1980s witnessed a sea-change in demographics, as New Orleans' growing African American middle class began moving into Eastern New Orleans in sizable numbers. More importantly, in the wake of the 1986 Oil Bust significant poverty was introduced into Eastern New Orleans, as many of the sprawling garden apartment complexes built in the 1960s and 1970s along I-10 to house upwardly mobile young singles began to accept large, poor, female-headed households as tenants. With increased poverty came increased crime rates, and both non-violent and violent crime became far more common than had been the case in the 1960s or 1970s. These changes were enough to induce a swift exodus of most of the white population, resulting in an Eastern New Orleans that was overwhelmingly African-American by 2005.
