Population studies is a branch of sociology that focuses on the study of human populations and their characteristics, such as size, growth, density, distribution, and composition. Population studies also examine the factors that influence population dynamics, including fertility, mortality, migration, and urbanization.
The scope of population studies is wide and interdisciplinary, encompassing a range of fields such as demography, anthropology, economics, geography, public health, and environmental science. This broad scope allows population studies to consider the complex interactions between individuals, families, communities, and societies, and how these interactions shape and are shaped by population trends and patterns.
The importance of population studies lies in its ability to provide valuable insights into a range of issues that have significant social, economic, and environmental consequences. For example, understanding population growth and composition can inform policy decisions related to education, healthcare, housing, employment, and infrastructure. Population studies also help to identify and address challenges related to population aging, urbanization, and migration, which have significant implications for social cohesion, economic development, and environmental sustainability.
Furthermore, population studies have important implications for global development and humanitarian efforts. By understanding the demographics of different regions and countries, organizations can tailor their programs and interventions to meet the specific needs and challenges of local populations.
In summary, population studies is a critical field of study that helps to shed light on the complex and interrelated factors that shape human populations and their impacts on society, the economy, and the environment. Its importance lies in its ability to inform policy decisions and global development efforts, and to identify and address challenges related to population dynamics.
Nature, Scope and Importance of Population Studies
Besides these too internal migration from one place to another place in particular State or country also plays a part. It is important to understand at this stage the meaning of population structure and population characteristics. This term covers all the measurable characteristics of the people of a given area or country. High population densities lead to frequent aggressive encounters, triggering a stress syndrome in which hormonal changes delay sexual maturation, cause reproductive organs to shrink, and depress the immune system Krohne 1984. Before delving any further into the details of the nature of population studies, it is important at this juncture to have a broad understanding of the various concepts used in the description of the scope of population studies.

It is also implied in this description that the subject matter of population studies includes the study of fertility, mortality, migration and social mobility, that is, the components of change in the size, structure, characteristics and distribution of population. Ecology and Scope of Ecological Studies: Ecology is that part of environmental studies in which we study about organisms, plants and animals and their relationship or interdependence on other living and non living environment. On the other hand, the population growth rates in the developed countries have declined to very low levels but they are facing other kinds of problems such as excessive urbanization, pollution and general environmental deterioration, and negative population growth. They are kept in view while fixing targets of agricultural and industrial products, of social and basic services like schools and other educational institutions, hospitals, houses, electricity, transport, etc. ADVERTISEMENTS: One important area of study covers the components of population change or the factors responsible for change in the size of population.

To sociologists, populationis the number of persons occupying a certain geographic area, drawing substance from their habitat, and interacting with one another. Individuals in these populations can have a hard time finding quality mates so, fewer individuals mate and those that do risk inbreeding Hamilton 1967. It is concerned with numbers and quantities and the relation between them. All crocodiles and many reptiles utilize a strategy called environmental sex determination, wherein incubation temperature determines the sex of each individual Delmas et al. Environment literally means Surrounding in which we are living. Sex RatioSexually reproducing organisms must find mates in order to produce offspring.

Population Geography Nature and Scope
The growing availability of population data after the Second World War facilitated mapping of the other demographic attributes pertaining to different regions of the world. What are the causes of deaths and how do these vary with age and sex? This article reviews some of this recent work, and argues that the issues at the core of critical migration studies are also those animating the discipline of geography more broadly. An analysis of dispersal in an unmanipulated population of Peromyscus leucopus. It focuses on the characteristics of population distributions that change in a spatial context. There are other factors such as marriage, divorce, social mobility change in social status and conditions which although do not affect the total size of the population but do determine the structure and composition of the population. Researchers then create a profile of the size and age structures of the cohorts to determine the reproductive potential of that population, in order to estimate current and future growth.

Population Studies
The main purposes are to create awareness to provide knowledge and develop responsible attitude and behaviors as well as improving the population to ensure a better life now and in the future. Population structure numbers, density, sex, and age , fertility, mortality, and migration are fundamental demographic variables. Major areas studied include broad population dynamics; fertility and family dynamics; health, aging, and mortality; and human capital and labor markets. The location of the population both throughout the cou ntry and within its regions andthe territorial organization of the population are basically determin ed the nature and geography of production. What is an example of a population in nature? ADVERTISEMENTS: Population structure implies the age and sex structure of the population and population characteristics include such characteristics as marital status, literacy and educational status, labour force status, etc. These questions clearly indicate that the study of population is concerned with its size or numbers, its structure and characteristics, its distribution and the changes taking place in it over a period of time.

Introduction to Population Demographics
Just as a doctor can't diagnose an illness with only a blood pressure measurement, we can't manage populations based on demographic parameters alone. SummaryA population is a group of individuals of the same species interacting within the same space. Science 156, 477-488 1967. It is also implied in this description that the subject matter of population studies includes the study of fertility, mortality, migration and social mobility, that is, the components of change in the size, structure, characteristics and distribution of population. It generally covers the areas as environment and enterprise objectives, scope, and structure of the environment, interaction of nature, society and the enterprise, environment impact assessment, economics of pollution, prevention, environmental management standards etc.

Environmental Studies: Nature, Scope and Importance
Thompson in his book entitled Population Problems described population studies as being concerned with the following questions related to three broad areas of study: 1. The nature of population geography is a wide range of synthesis among different demographic dynamic. As Panopio states, demographic data are important for the formulation, implementation, and evaluation of plans, policies, and programs for education, housing, health, employment, transportation, recreational needs and other forms of social services. They include a set of demographic characteristics such as structure, marital status and average age at marriage etc. Thus persons who are not part of a collective group, who are not situated within the geographical limits and who are not living, or who have died during the time of the population count are definitely not included in the so-called population. It must be understood that the population of any place at a specific time is a function of three types of events: births, deaths and migration. Emigration means the process of leaving one country to take up residence in another.

Importance of population studies
Population size is defined as the number of individuals present in a subjectively designated geographic range. Mortality is the measure of individual deaths in a population and serves as the counterbalance to fecundity. Population geography implies the investigation into human covering of the earth and its various facets with reference to physical and cultural environment. A population is defined as a group of individuals of the same species living and interbreeding within a given area. They are migration and urbanisation which lead to the coming up of shanty towns, pollution, drainage, water, electricity, transport, etc. Proyer suggested that population geography deals with the analysis and explanation of interrelationship between population phenomena and the geographical character of places as they both vary over space and time Proyer, 1984:25. Despite the simplicity in its concept, locating all individuals during a census a full count of every individual is nearly impossible, so ecologists usually estimate population size by counting individuals within a small sample area and extrapolating that sample to the larger population.
