Census A census is an official enumeration of population done periodically. In India, the first census was held in the year 1872. The first complete census, however, was taken in the year 1881. Since then, censuses have been held regularly every tenth year. The Indian Census is the most comprehensive source of demographic, social and economic data. Have you ever seen a census report? Check in your library if it has one. 48 CONTEMPORARY INDIA-I  POPULATION India’s Population Distribution by Density Rest of the world, 82.5% Population density provides a better picture of the uneven distribution. Population density is calculated as the number of persons per unit area. India is one of the most densely populated countries of the world. India, 17.5% Only Bangladesh and Japan have Do You Know higher average population densities AREA than India. Find out the population densities of Bangladesh and Japan. Rest of the world, 97.6% The population density of India in the year 2011 was 382 persons per sq km. Densities vary from 1,102 persons per sq km in Bihar to only 17 persons per sq km in Arunachal India, 2.4% Pradesh. A study of the Figure 6.3 shows the pattern of uneven distribution of population Fig 6.1 : India’s Share of World’s Area and Population densities at the State level.

The questionnaire should contain minimum five questions. Questions should relate to students, their family members, their class performance, their health, etc. Each student is required to fill in the questionnaire. Compile the information in numerical terms (in terms of percentage). Present the information through pie-chart, bar-diagram or in any other way. 54 CONTEMPORARY INDIA-I  G LOSSARY Adolescence : Adolescence is a period in which a person is no longer a child and not yet an adult. Such persons are grouped in the age group of 10 to 19 years. Alluvial plain : A level tract of land made up of alluvium or fine rock material brought down by a river. Base population : The total population of an area at the beginning of a given time period. Biome : Plant communities occuring in distinct groups in areas having similar climatic conditions. Birth rate : The number of live births for every 1000 persons in a year.

In geology, it refers to a hollow sunken area of the earth’s surface. Death rate : The number of deaths per 1000 persons in year. Density of population : The average number of persons per unit area, such as a square kilometre. Dependency ratio : The ratio of people of dependent age (below 15 and above 60 years) to people of economically active ages (15-59 years). Ecosystem : A system which comprises the physical environment and the organisms living therein. Environment : Surroundings or the conditions under which a person or thing exists and develops his or its character. It covers both physical and cultural elements. Fault : A linear break in rocks of the earth’s crust along which there has been displacement in a horizontal, vertical or oblique direction. Fauna : The animal life of a given area. Flora : The total vegetation or plant cover of a region. Fold : A bend in the rock strata resulting from compression of an area of the earth’s crust. Geosyncline : A narrow, shallow, elongated basin with a sinking bottom in which a considerable thickness of sediments was deposited by the rivers coming from Angara and Gondwanaland. Glacier : A mass of snow and ice that moves slowly under the influence of gravity along a confined course away from its place of accumulation. Growth rate of population : The growth rate of population indicates the rate at which the population is growing. In estimating the growth rate the increase in population is compared with the base population. It can be measured annually or over a decade. Indian mainland : It refers to the contiguous stretch of landmass from Jammu and Kashmir to Kanniyakumari and from Gujarat to Arunachal Pradesh. Indian Standard Time : The local time along the Standard Meridian of India (82°30'E). Inland drainage : A drainage system in which the waters of the rivers do not reach the oceans but fall into an inland sea or lake. Igneous rocks : Rocks formed as a result of solidification of magma either below the earth’s surface or above it. Lagoon : A salt-water lake separated from the sea by the sandbars and spits. Lake : A body of water that lies in a hollow in the earth’s surface and is entirely surrounded by land.

Plateau : An extensive elevated area of relatively flat land. Plate tectonics : The scientific concept that explains the movements of the crustal plates. Relief : The differences in elevation or the physical outline of the land surface or ocean floor. Subsidence : In meteorology, it is the downward movement of the air. In geology, it refers to the sinking of a portion of the earth’s surface. Sedimentary rocks : Rocks composed of sediments and generally having a layered structure. Sex-ratio : Sex-ratio is defined as the number of females per thousand males. Subcontinent : A big landmass, which stands out as a distinct geographical unit from the rest of the continent.
