STATISTICAL ANALYSIS ON THE IMPACT OF BIRTH AND DEATH RATES ON NIGERIA’S ECONOMY (2000–2015)

CHAPTER ONE

1.1 BACKGROUND OF THE STUDY

Economic Growth and Population Dynamics

Nigeria’s economy has experienced inconsistent growth over the years, despite visible efforts toward reform and industrial expansion. Achieving stable economic development is crucial for national progress and improved living standards. To understand these fluctuations, several economic determinants must be examined closely. Among these, birth and death rates play a key role in determining a nation’s socio-economic structure.

A strong and sustainable economy depends heavily on population size and productivity. As the population increases, the demand for goods, services, and infrastructure rises as well. Conversely, when the death rate is high, the labor force may decline, reducing overall productivity. Therefore, both factors—birth rate and death rate—directly influence consumption levels, investment patterns, and government planning.

Understanding the Birth Rate

According to the World Bank (2013), Nigeria’s crude birth rate stood at 41.24 births per 1,000 people. This measure reflects the number of live births per year per 1,000 individuals, typically calculated at mid-year. When the death rate is subtracted from the birth rate, the outcome represents the natural population growth rate, assuming no migration occurs.

Globally, the average birth rate in 2012 was 19.15 births per 1,000 people, showing a slight decline from 20.09 births per 1,000 recorded in 2007. These statistics are obtained through national population censuses and registration systems. Birth rates, when combined with mortality and migration data, are critical in projecting population trends and economic performance.

Understanding the Death Rate

The death rate, also called the mortality rate, measures the number of deaths per 1,000 people in a specific period. It is a vital indicator of a nation’s healthcare quality, living conditions, and economic wellbeing. For example, a death rate of 9.5 per 1,000 implies that approximately 9.5 individuals die each year out of every 1,000 citizens.

High death rates may indicate poor healthcare, poverty, or inadequate infrastructure. Conversely, a low death rate often signals improved living conditions and better access to medical services. Therefore, both indicators must be studied together to understand how demographic changes affect economic outcomes.

Economic Implications

Changes in population size influence the labor force, consumer demand, and government expenditure. An increasing birth rate can boost the labor market in the long term but may also strain resources in the short run. Similarly, declining death rates can expand the active workforce, leading to greater productivity and output. Consequently, analyzing these demographic indicators helps predict Nigeria’s economic direction and supports better policy formulation.

1.2 STATEMENT OF THE PROBLEM

Nigeria’s economy has long struggled with instability and poor planning. One major challenge is the inadequate consideration of population factors—particularly birth and death rates—in economic forecasting. The absence of reliable demographic records makes it difficult to evaluate growth patterns and design effective policies.

Furthermore, many development strategies ignore how population changes affect labor, production, and social services. Without accurate birth and death data, the government cannot effectively allocate resources or forecast future economic trends. This study, therefore, investigates how these factors influence the overall performance of the Nigerian economy.

1.3 OBJECTIVES OF THE STUDY

The major objective of this research is to analyze the impact of birth and death rates on Nigeria’s economy between 2000 and 2015.

The specific objectives are to:

1. Examine the relationship between birth rate and Nigeria’s economic growth.

2. Investigate how the death rate affects Nigeria’s economy.

3. Forecast Nigeria’s economic performance using both birth and death rates.

4. Determine the nature of the relationship among birth rate, death rate, and economic performance.

1.6 SIGNIFICANCE OF THE STUDY

Accurate demographic data are vital for sustainable economic planning. This research aims to help government agencies, researchers, health institutions, and policymakers understand how birth and death rates influence Nigeria’s economic growth.

By emphasizing the importance of proper data documentation, this study encourages better decision-making in areas such as employment, healthcare, population control, and national budgeting. It also serves as a reference for future studies focusing on the interaction between population dynamics and economic development.

1.7 SCOPE OF THE STUDY

This research focuses on the relationship between birth and death rates and economic performance in Nigeria from 2000 to 2015. Data were obtained from national statistics and institutional sources, particularly the Braithwaite Memorial Hospital (BMH), Port Harcourt, to illustrate demographic trends at the local level.
