populations obtained from the listing were systematically smaller by about 46 percent (Table A.2) thanthose from the Demarcation Exercise. This discrepancy suggested that the Demarcation Exercise wasproducing serious overestimates of the population. An adjustment was therefore introduced for this in thenext step.Second Stage SelectionThe relationship between sample selection fractions is as follows:f(2) = F/f(1).Thus, before f(2) could be calculated, a value for the overaU sampling fraction, F, was needed and thisrequired an estimate of the population of Ondo State. At the time of second stage sample selection(August 1986), three sources of population information were available: the 1963 Population Census, theEnumeration Area Demarcation Exercise and the household listing operation of the ODHS survey. Asshown in Table A.1, the population estimate for the 13 LGAs covered by the Enumeration AreaDemarcation Exercise (2,674,734) indicates an increase of 22 percent over the 1963 Census Populationfor those LGAs (2,193,603). Assuming equal growth in the 4 remaining LGAs, a total populationestimate for Ondo State would be 3,329,856 (2,729,390* 1.22).Table A.IPopulation Estimates for Ondo State, by Local Government AreaPopulation Estimate1963 EA Demarcation ExerciseLocal Government Area Census 1984-8601 Akure 129,415 400,43502 Akoko North 153,311 282,16503 Ekiti East 123,649 156,72004 Ero 224,088 173,27705 Ekiti South 220,076 151,61906 Ekiti Southwest 124,044 87,30407 Ekiti Central 262,337 212,41008 lJero 133,963 117,49009 Ekiti West 171,347 143,555I0 Akoko South 131,508 165,735Ii Ekiti North 181,455 253,11112 Owo 189,847 322,27313 Idanre Ifedore 148,596 208,64014 Ondo* 148,734 --15" Ifesowapo* 109,330 --16 Ilaje Eseodo* 93,926 --17 Ikale* 183,797 --TOTALS - All LGAs 2,729,390 --LGAs 01-13 2,193,603 2,674,734*The EA Demarcation Exercise was not completed in four LGAs at the time ofsample selection.78
