INTRODUCTION

In an earlier 'Saturday Essays' of October 3, 1998, which I reproduce
below, I wrote the following:

The present controversy over presidential election figures has provided me
another incentive to ask the pertinent:  how many Nigerians are there
really?

I have come to a hand-wavingly 'accurate' figure:  58,405,755.  That is,
we are really about half of what we are cracked up to be!

How did I arrive at this figure?  Please follow me closely.

THE CALCULATIONS

So far there have been three official censuses in Nigeria:

Estimate 1 is given in the CIA Factbook, with a website

of 244 million is given in the following news report of March 23, 1999:

World Population Seen At 9 Bln By 2050

Tuesday, March 23, 1999
By Anthony Goodman

UNITED NATIONS (Reuters) - The world's population, expected to reach six
billion in October, will be nearly nine billion by the year 2050,
according to the latest U.N. estimate Monday.

``Fifty years from now, the U.N. Population Division projects a much
larger world population than exists today. We are anticipating a world
close to nine billion inhabitants,'' the division's director, Joseph
Chamie, told the U.N. Commission on Population and Development.

But he said a U.N. projection for the year 2000 calculated 40 years ago
was remarkably accurate in predicting a figure of slightly more than six
billion, even though in the aftermath of World War Two, when the world
population was slightly above two billion, few believed it would nearly
triple by the end of the century.

Chamie said the population increase of some three billion by the year 2050
was expected to take place in less developed regions.

He said India alone would grow by 50 percent in the next five decades,
from one billion to 1.53 billion, and would be the largest country in the
world.

Nigeria and Pakistan would both grow even more rapidly, by roughly 120
percent -- from 156 million to 345 million for Pakistan and from 112
million to 244 million for Nigeria.

China now has the world's biggest population. Chamie gave no figure but it
is generally estimated at some 1.2 billion.

But he said China's fertility rate, which in 1950 was among the world's
highest with approximately 6.2 children per couple, was now well below
replacement level, at 1.8 children per couple.

Chamie gave no reason for this but Beijing enforces a strict ``one child
per family'' birth control policy.

He said that between now and 2050, the populations of 30 countries were
projected to decline. They include Germany, from 82 million to 73 million;
Japan, from 126 million to 105 million; and Russia, from 147 million to
121 million.

UNQUOTE

That total estimate for Nigeria is rather alarming!  However, it means an
unrealistically 1.54% growth rate over about 50 years from 112 million to
244 million:  the 112 million is either too low or the 244 million is too
high!

Now the 1953 census figure of 31.6 million is reported to be about a 10%
undercount.  If we therefore assume a 1953 population of 35 million, and
project an increasing growth rate as each decade progresses, we get the
following table of estimates:

------------------------------------------------------------------------
Table 2:  Estimates of Nigerian Population Figures Based on 1953 Figures
-------------------------------------------------------------------------
Year        Estimates   Growth Rate  Comments
1953          35          2.25      figure assumes 10% undercount
1963          43.7        2.50      - growth rates indicate improving
1973          55.9        2.75        health conditions
1991          91.1        3.0         up until 3.0
1998         112.0        2.75      g.rate reduction due to family plan.
2050         459                    alarmingly high figure!
-------------------------------------------------------------------------

Again, we recover a population of about 112 million in 1998, but with an
estimate of 459 million  Nigerians in the year 2050!

We can only accurately obtain our population by conducting a credible
census.  In the time being, is there a way to better estimate how many we
are?

I believe that by looking at the countries surrounding Nigeria - Benin,
Togo and Ghana to the west, Cameroon to the east and Niger and Chad to the
north - and assuming that there POPULATION DENSITIES are correct, we can
begin to CALCULATE an ESTIMATE for Nigeria.

The basic information is presented in the following table, and is
obtained from the CIA Factbook for each country:

Note on military issues: number of personnel available, fit for military
service and reaching military age annually are all in millions.  For each
country, all numbers are for males, except for Benin, which also supplies
female figures (second number.)
--------------------------------------------------------------------------

Now Benin, Togo and Ghana are all below the Niger to the west of Nigeria,
Cameroon below the Benue to the east of Nigeria and Chad and Niger are far
to the north of the Niger and Benue.  We will assume that these
neighboring countries' population densities are AKIN to the actual
population densities of various STATES within Nigeria (being close to
them.)  In fact, we DOUBLE/or TRIPLE their population densities
accordingly to obtain the estimates for the akin states.

*Note:  110 is double of average of 75 and 32.  20 is TRIPLE of 7.  65 is
average of 110 and 20.

Thus we get a population estimate of 58.4 million, with an average
population density of 63 persons per square kilometer.

Hopefully, in the next civilian administration, getting our accurate
census is a task that must be done.

Best wishes all.

Where do Nigerians live, and what is their population densities AND their
distribution nation-wide?

Below, in two tables, I have tried to inspect some data based on the 1991
census count for 30 states + Abuja, and reliable area data for the
nineteen pre-1991 states. New states and former states have also been
taken into account in some aggregate fashion.

Some Observations
-----------------

It is interesting to note from the above data that while the whole of
Nigeria has an average population density of about 100 persons per square
kilometer, Lagos State has about 16 times that number, which gives an
indication of the congestion of that state and drift to the economic
center of Nigeria.  Next to Lagos State is Imo State, which has about
four-and-a-half times the average Nigerian population density.  The least
is Niger State, with about one-third the average population density of the
country.

On a regional basis, the South-Eastern region (Igboland), despite being
the region with the least population AND least land mass, has the highest
population density which is about three-and-an-half times that of the
National average.  On the other hand, we have the North-West region
(Sokoto-Kebbi-Niger axis), which has the largest land mass and only about
a million persons more that the South-East region, but it has just over
one-tenth the population density of the South-East.

On a North-South basis, the North has about four times the land mass of
the South, and just 6% more in population.  This results in the South
having just over twice the national average in populatin density, while
the North is about two-thirds of the national average.

Conclusion
----------

No nation can progress properly without accurate data about not only its
population, but its population density.  Population density in particular
is important in terms of provision of services, agriculture and food
availability and potentials for voluntary migration/planned resettlements
(?) due to efforts to ease congestion and improve the quality of life.

It will serve us well if our nation makes a greater effort to get accurate
information and put all of these issues into consideration during national
planning.

Best wishes all.
