ABSTRACT
COMPUTERIZED Population analysis system includes
the sets of methods that allow us to measure the dimensions and dynamics of
populations. These methods have primarily been developed to study human
populations, but are extended to a variety of areas where researchers want to
know how populations of social actors can change across time through processes
of birth, death, and migration. In the context of human biological populations population
analysis uses administrative records to develop an independent estimate of the population.
Computerized Population analysis system estimates are often considered a
reliable standard for judging the accuracy of the census information gathered
at any time. In the labor force population analysis is used to estimate sizes
and flows of populations of workers; in population ecology the focus is on the
birth, death and movement of firms and institutional forms.
ORGANIZATION

This project
work is primarily designed to give an insight to Computerized Population
analysis system.
Chapter one
talks about introduction to Population analysis, study of problem and objectives as
well as definition of the scope.

about the existing (old) system, while chapter four and five deals with the
design and implantation of new system.
Chapter six
document the project work, while chapter seven summaries, conclusion and suggestions were made.

INTRODUCTION
Population Census
is the statistical and mathematical study of the size, composition, and spatial
distribution of human populations and how these features change over time. Data
is obtained from a census of the population and from registries-records of
events like birth, deaths, migrations, marriages, divorces, diseases, and
employment. To do this, there needs to be an understanding of how they are
calculated and the questions they answers which is included in these four
concepts: population change, standardization of population numbers, the population
bookkeeping equation, and population composition.
Population
Change
Population change is
analyzed by measuring the change between one population size to another. Global
population continues to rise, which makes population change an essential
component to populations. This is calculated by taking one population size
minus the population size in an earlier census. The best way of measuring
population change is using the intercensal percentage change. The intercensal
percentage change is the absolute change in population between the censuses
divided by the population size in the earlier census. Next, multiply this by
100 to receive a percentage. When this statistic is achieved, the population growth
between two or more nations that differ in size, can be accurately measured and
examined.
Standardization (of population numbers)
For there to be a
significant comparison, numbers must be altered for the size of the population
that is under study. For example, the fertility rate is calculated as the ratio
of the number of births to women of childbearing are to the total number of women
in this age range (multiplied by 1000). If these adjustments were not made, we
would not know if a nation with a higher rate of births or deaths has a
population with more women of childbearing age or more births per eligible
woman.
Within the category of standardization,
there are two major approaches: direct standardization and indirect
standardization.
Direct Standardization
Direct
standardization is able to be used when the population being studied is large
enough for age-specific rate are stable.
Indirect Standardization
Indirect
standardization is used when a population is small enough that the number of
events (births, deaths, etc.) are also small. In this case, methods must be
used to produce a standardized mortality rate (SMR) or standardized incidence
rate (SIR)
Population
Composition
Population
composition is the description of population defined by characteristics such as
age, race, sex or marital status. These descriptions can be necessary for
understanding the social dynamics from historical and comparative
research. This data is often compared using a population pyramid.
Population composition is also a very
important part of historical research. Information ranging back hundreds of
years is not always worthwhile, because the numbers of people for which data
are available may not provide the information that is important (such as population size).
Lack of information on the original data-collection procedures may prevent
accurate evaluation of data quality.
STATEMENT OF PROBLEM
Owing to:
- The
difficulties encountered in keeping population data/information.
- Miscalculation
of population data/information,
- Difficulties
in accessing population data/information
- Time
wasted in searching for a given population data/information on packed files.
- Time
wasted in processing population data/information
The need arise for the development of computerized population
analysis system for national population commission Enugu.
- PURPOSE
OF STUDY
The main purpose of this study is to eliminate
errors involved in population data/information. This is actualized by designing
computerized population analysis system for national population commission
Enugu which is user friendly and interactive. By the time this software is
designed and implemented, the difficulties encountered with manual method of
keeping population information will be eliminated.
- SIGNIFICANCE
OF STUDY
With the growth in information
technology, the study offers numerous values to the national population
commission Enugu.
Huge of files kept in the offices
will no longer be there again because information will be stored on the
computer with the help of the database program.
- AIMS
AND OBJECTIVES
The aims and objectives of this project is listed below:
- To provide essential information for government decision
making
- To enable people understand their community
- To eliminate gaze work in population census.
- To
demonstrate increased motivation to the census workers.
- To
easy the work associated with manual method analyzing population
data/information.
- To
eliminate the error involved with the manual method analyzing population
data/information.
- To
save the time wasted when method analyzing population data/information.
- To make
population council office neat and tidy as a lot of information will no
longer be documented on paper but in computer.
- To
ensure easy retrieving and updating of population data/information.
- SCOPE
OF STUDY
This project work is narrowed to computerized population analysis system for national population commission Enugu. It also deals with the development of database program to help in the storage of population data/information in the national population commission Enugu.
- LIMITATION
OF STUDY
Owing to the scope of this project work as stated above, this project work is limited to computerized population analysis system for national population commission Enugu.
It is important to mention here that time was a major constraint in the course of fact finding. It is also wise to mention here that some information we need to work with were not collected because of some reason.
