The study examined the influence of socioeconomic attributes of residents on domestic solid waste disposal methods in Lagos metropolis, Nigeria. Primary data for the study were obtained through questionnaire administered on residents in Eti-Osa, Ikeja, and Mushin Local Government Areas (LGAs) representing the low, medium, and high densities, respectively, into which the sixteen LGAs in Lagos metropolis were stratified. One out of every four wards in each LGA was selected for survey. From a total of 15,275 residential buildings in the ten wards, one out of every forty buildings (2.5%) was selected using systematic random sampling where a household head was sampled. Information obtained includes the residential characteristics and the disposal methods. Enquiries into the socioeconomic attributes of the residents showed that 59.9% were high income earners and 76.6% had attained tertiary school education. This study concluded that six disposal methods were common in the study area. Furthermore, through multinomial logistic regression, the influence of socioeconomic characteristics of residents (density, income, age of respondents, educational status, and length of stay) on domestic solid waste disposal methods varied significantly in Lagos metropolis. The study established that most of the solid waste disposal methods utilized by residents in Lagos metropolis were not environment-friendly. 1. Introduction The rapid urbanization experiencing in the cities of the world has accentuated for a plethora of environmental challenges within the different residential spheres. These problems include urban sprawl, decaying inner-city, inadequate housing, crime, and congestion, among others. Of pertinent attention is the problem associated with waste management that is taking unprecedented complex dimension in the cities of developing nations. From engineering to behavioral science, how waste can be properly managed has become a germane issue via several studies [1–4]. An elaborate definition of the term waste embraces all unwanted and economically unusable by-products or residuals at any given place and time and any other matter that is discarded into the environment [5, 6]. This definition suggested that what constitutes waste must occur in such a volume, concentration, constituency, or manner as to cause a significant alteration in the environment. Thus, apart from waste being an unwanted substance that is discarded, the amount of it and the impact it makes on the environment also become important considerations in defining waste.
