This paper examined the factors influencing the emergence and expansion of informal waste collection in waste management sector of Ibadan, the Oyo State capital. Snowball sampling technique was used to identify and sample 253 informal waste collectors across the five municipal local government areas in the city. A pretested structure questionnaire was used to obtain information from the sampled informal waste collectors. Data collected were analysed using Relative Importance Index (RII), 8 x 8 correlation matrix and factor analysis. Eight major factors were identified as influencing the emergence and expansion of informal waste collection. RII showed that in ranked order of importance, they are: poverty; unavailability of better job; profitability; demand for waste management service; low start-up capital; ease of entry; pressure from parents and guardians and low-skill requirement. The correlation matrix indicated that all the factors correlated positively with one another. The Kaiser-Meyer-Olkin Measure of Sample Adequacy (KMO) value of 0.573 and Bartlett’s Test of Sphericity of p≤ 0.001 established the adequacy of the variables loaded for the analysis. It is concluded that policies and programmes that will enhance integration of IWCs to municipal waste management scheme of the city and check child labour in the sector will go a long way in making the sector more effective in municipal waste management.
