The work compares vulnerability to eviction in slums of the South-western States. Multistage sampling technique was employed to obtain primary and secondary data used. One out of the identified slum nieghbourhoods in the capital cities of the six states was statistically selected. Google Earth was used to delineate the slum areas and count the number of houses, copies of questionnaire were administered on the 20% (20th) residential houses head. 1207 copies of questionnaire were administered in total but 1057 were retrieved and used. ANOVA in SPSS was used to analyze the data; compare the findings and test the set hypothesis. The work discovered that the slums at core of the cities are the worst and most vulnerable to eviction because the properties do not have any form of legal papers, evicted slum residents are becoming serial evictees and poverty and homelessness is aggravated since most evictions are arbitrary and negate human right laws and international conventions. All slum residents are vulnerable to eviction, they are perturbed and there is no statistically significant difference in the level of vulnerability of eviction across the slums of South-western States of Nigeria. Slum residents need to strengthen their position against arbitrary eviction using different approaches. Planning tools that regulate unnecessary pressure on CBD land must be applied and human right must be accorded the expected respect economic status notwithstanding.
