“…Consequently, the country relies upon data estimates and forecasts which have typically and consistently come from global institutions such as the International Monetary Fund and The World Bank (Kazeem, 2019). The consensus across academia and recent assessments of the challenges related to Nigerian data (Nwogu, 2006;Olubusoye et al 2015;Beguy, 2016;Afeye, 2019;Kazeem, 2019;Uduu, 2020) is that data is not easily available due to systemic deficiencies mainly of governance (poor coordination, inadequate monitoring and evaluation) and funding (which is largely-donor driven).…”

A Review of the Property Data Challenge in Nigeria

Data on Nigeria’s property sector tends to be inadequate and inaccessible. While the government produces statistics for its own activities, such as GDP and inflation rates, other sectors function with insufficient information. This is particularly true for Nigeria’s property sector and its data which have been given a lesser status despite an increasing economic importance for investment opportunity, GDP contribution and attraction of foreign investment funds. The gap in data creates a challenging situation for property valuers, but also, an opportunity for property researchers. This paper, which reviews existing literature on the subject, is a contribution to the debate as well as an effort towards a solution. The literature stipulates that poor accessibility to property data leads valuers to enact coping mechanisms rather than best practice and that property data is synonymous with market transactions which makes it invaluable to valuers. Also, there is a convergence of views in the reviewed literature that a central data bank offers opportunities for a solution. Conversely, it is here argued that focusing on market transactions is a narrow understanding of data as property data extends beyond such transactions. This school of thought believes that the users and uses of property transaction data extend beyond valuers and valuations and that the central data bank recommendation requires examination as to its feasibility. Accordingly, this paper broadens the definition of property data by recognising the existence of non-market data, by identifying its other users and uses as well as its role in socio-economic policies. The considerable doubts associated with the central data bank recommendation leads the study to make recommendations which are novel, but nevertheless, hold holistic methods for addressing Nigeria’s property data challenge.

“…It has been shown that the quality of reported age and sex data from the Nigerian population censuses are grossly defective; adjustment has been recommended for any meaningful usage of the reported census data, especially for the estimation of demographic parameters and developmental planning implementation in Nigeria (Ekanem, 1972;Nwogu, 2006;Ohaegbulem, 2015;Nwogu & Okoro, 2017). Nwogu & Okoro (2017) adjusted the reported populations in the Nigeria censuses using mathematical methods (such as the Carrier Farrag method, the Newton Halving method, and the United Nations Five-point method etc.).…”

This paper focuses on the estimation of adult mortality in Nigeria. The general objective is to obtain adult mortality levels for Nigeria which may be relevant in assessing the level of development and the progress of Sustainable Development Goals (SDGs) in that country. Census-based methods were applied to the 1991 and 2006 adjusted population census by age and sex to estimate adult mortality. The results of the study suggest that adult males in Nigeria have a higher life expectancy than their female counterparts in almost all age groups. At age 5-9, the life expectancy from the methods applied was below 60 years. The consequences of low life expectancy among adults include the early marriage of young girls, an increasing orphanhood burden, and high numbers of out-of-school children, which may hamper the achievement of SDGs in the country. Given that there is no consensus yet on the best approach for estimating adult mortality in developing countries, we recommend that censusbased methods should be used for this task.

“…In most developing countries data on adult mortality come from censuses and sample surveys [2,1]. Data from these two sources have been shown to be defective, hence the resort to indirect techniques for its estimation in developing countries [3,1,4,5,6,7,8,9,10].…”

This study proposes a modified Preston-Bennett method for the estimation of adult mortality in developing countries. Unlike the previous method, the proposed method derives estimates of adult mortality directly from the 5-year age distribution at the mid-point of the inter-censal period. In other words, it does not convert the 5-year age distributions to single years before estimation. Results obtained from empirical studies compared favourably well with those from the original Preston-Bennett method and therefore, recommend for the estimation of adult mortality in developing countries.
