The problem associate with population census is the phenomenon of ethnicity and religion brought to Nigeria among other negative impacts includes discrimination ,corruption ,politics of federal character .Ethnic consciousness and as well as religious consciousness brings about disunity among the people of Nigeria which always result to internal conflict and thereby hinders the development planning in Nigeria. Such as economic development, social and cultural development which could also be regarded a major problem in Nigeria.
Population census is always carried out in Nigeria in order to know the actual figure of Nigerian citizens to enable them share the revenue allocation .It is important to note that religion is one of the factors that contributed to hinderance for the successful population census ever conducted in Nigeria .For instance the Muslim people doesn’t allow their women to be count,reason been that their culture does not permit such, that is why the northern figure is always higher than any other ethnic group in Nigeria and it brought about discrimination among the major ethnic group in Nigeria.
Record doctoring is also a major problem facing the population census in Nigeria. Religious bias remote areas and financial issues are just a few of the reasons behind the alterations. Nigeria is a country in religious chaos (crises).Ten thousands of Nigerians has been killed in the past decade in the name of ethnic and religious. Because one religion or the other group of religion may have a special interesting claiming power over another through numbers and because Nigeria’s religious population is primarily split between the north and south, there is longstanding dispute about whether the numbers that reflect a significantly larger population in the north are accurate or simply the result of altered records.
Another reason to believe that records doctoring maybe a problem for the Nigerian census is the distribution of wealth versus natural resource. Oil is major money maker for Nigeria. The majority of the country’s oil comes from the south of the country, but the north controls most of the money. The fact that a significant portion of the population lives in remote areas is another issue. Quit, simply it is difficult for census workers to reach many of the country’s people to record how many there are and because there are no significant records to document births and deaths. Therefore, it is difficult to verify the information on census forms.
Falsification of population census result. In counting of population census in Nigeria due to past experience of the census conducted in 2006, the demographic data were said to be also deliberately falsified; thus the population was exaggerated in the published results. Also apart from this case of deliberate falsification, the authorities were also corrupt, because they are the ones who gingered the motion. The census committee in the 2006 population census in Nigeria were been rebuked by foreign agencies for introducing 20 sstrategie rather a deceptive tactic of data falsification of result.
