A value of 0 means that the land in the neighbourhood is exclusively dedicated to a single use, while a
value of 1 indicate perfect mixing of the land uses.
Socio-economic characteristics considered in the analysis include sex, age, marital status, income,
educational level, occupation, vehicle availability, household size, number of children schooling (less
than 18 years), and number of children working.
3.2 Data Collection Procedure
The primary data used in this study was obtained from a field survey undertaken in 2006 in the urban part
of Ibadan metropolis. The survey was a seven day travel diary of households. The information sought in
the activity survey included the travel mode, frequency, cost of travel, travel time, origin and destination
locations for various travel purposes. A questionnaire survey was used to obtain information on individual
socioeconomic characteristics. Three neighbourhoods were selected from each of the five local
government areas to reflect varying population size, income group, location vis- a- vis the city centre and
the traditional nature of Ibadan. In each of the neighbourhoods surveyed, the numbers of streets were
identified and a random selection made. On each street, systematic random sampling technique was
employed to select the housing units involved in the survey. The size of the sample in each location was
based on the population size of the area. The travel diary and questionnaire was administered on eight
hundred and sixty-six respondents (table 1). However, only seven hundred and seventy-nine respondents
provided the required information. This represents a response rate of 90 %.
In addition to the primary data source, secondary data on population size of each local government area
was obtained from the National Population Commission. Information on land area and area dedicated to
each land use (residential, commercial, industrial, recreational and open spaces) in each local government
area was obtained from a land use GIS shape file.
4. Study Area
Ibadan, the study area, is defined by Longitude 582497.53E and 619034.53E and Latitude 797984.42N
and 834692.42N at a distance of about 145 kilometres north east of Lagos. The area has been witnessing
large scale in-migration since it became the headquarters of the western region and later the capital of
Oyo state. The areal extent of the metropolitan area of the city increased from 302.54 squares in 1984 to
325.68 square kilometre in 1990 and 417.92 square kilometre in 2000. Similarly the population of Ibadan
metropolis increased from 1 222 570 in 1991 to 1 338 659 in 2006. Ibadan metropolis is made up of a
total of eleven local government areas. The urban part of the metropolis comprise of five local
government areas, namely, Ibadan North, Ibadan North West, Ibadan North East, Ibadan South West and
Ibadan South East. Ibadan is one major Nigerian city that was for a long time allowed to grow without a
land use plan. Consequently, there is a great mix of activities such as residential, commercial, residential
and industrial, especially small to medium sized establishments. However, the government has through
the Ibadan Municipal Planning Board, instituted measures that are leading to the emergence of discernible
patterns of land use in the area.
