    Doubling time is the amount of time it takes for a given quantity to double in size or value at a constant growth rate. We can find the doubling time for a population undergoing exponential growth by using the Rule of 70. To do this, we divide 70 by the growth rate (r).

    The doubling time is time it takes for a population to double in size/value. It is applied to population growth, inflation, resource extraction, consumption of goods, compound interest, the volume of malignant tumours, and many other things that tend to grow over time. When the relative growth rate (not the absolute growth rate) is constant, the quantity undergoes exponential growth and has a constant doubling time or period, which can be calculated directly from the growth rate.

    This time can be calculated by dividing the natural logarithm of 2 by the exponent of growth, or approximated by dividing 70 by the percentage growth rate[1] (more roughly but roundly, dividing 72; see the rule of 72 for details and derivatiatives of this formula).

    The doubling time is a characteristic unit (a natural unit of scale) for the exponential growth equation, and its converse for exponential decay is the half-life.

    Population growth is determined by the annual growth rate, which is calculated in percent per annum. Like, if there is an increase of two people per 100 people of the population, then the annual growth rate would be 2%.

    Non-conventional energy sources are the alternatives to conventional sources of energy as former are exhaustive in nature and take longer time i.e. million years to replenish them. So, it is important for us to adopt some values in our lives to save these precious sources, for e.g: Create awareness about sustainable development and the use of non-conventional sources. Try to inculcate the habit among masses, not to waste these sources and save for future generation also. Create awareness about cost-effective. More pollution in the environment i.e. water, air, land and soil pollution, need high technology to combat such situations which is very costly.

    Density of Population:

    • Population density is the number of people living in a unit area of the earth’s surface.
    • It is normally expressed as per square km.
    • The average density of population in the whole world is 51 persons per square km.
    • South Central Asia has the highest density of population followed by East and South East Asia

    Distribution of Population: Population growth refers to the change in number of people living in a territory during a specific period of time. This change may be positive or negative. It is usually expressed in terms of percentage or absolute numbers.

    • The way in which people are spread across the earth's surface is known as the pattern of population distribution. More than 90 percent of the world’s population lives in about 30 percent of the land surface.
    • The crowded areas are south and south east Asia, Europe and north eastern North America. Very few people live in high latitude areas, tropical deserts, high mountains and areas of equatorial forests.
    • Many more people live north of the Equator than south of the Equator.

    Gorwth of Population: Population growth refers to the change in number of people living in a territory during a specific period of time. This change may be positive or negative. It is usually expressed in terms of percentage or absolute numbers.

    Settlements are classified on the basis of their shape, patterns types which are discussed below: • Compact or Nucleated settlements: In these settlements large number of houses is built very close to each other. Such settlements develop along river valleys and in fertile plains. Communities are closely knit and share common occupations. Dispersed Settlements: In these settlements, houses are spaced far apart and often interspersed with fields. A cultural feature such as a place of worship or a market, binds the settlement together Rural Settlement Patterns Patterns of rural settlements contemplate the way the houses are sited in relation to each other. The site of the village, the surrounding topography and terrain influence the shape and size of a village. Rural settlements may be classified on the basis of a number of criteria: (i) On the basis of setting: The main types are plain villages, plateau villages, coastal villages, forest villages and desert villages. (ii) On the basis of functions: There may be farming villages, fishermen’s villages, lumberjack villages, pastoral villages etc. (iii) On the basis of forms or shapes of the settlements: These may be a number of geometrical forms and shapes such as Linear, rectangular, circular star like, T-shaped village, double village, cross-shaped village etc. • Linear pattern: In such settlements houses are located along a road, railway line, and river, canal edge of a valley or along a levee. • Rectangular pattern: Such patterns of rural settlements are found in plain areas or wide inter montane valleys. The roads are rectangular and cut each other at right angles. • Circular pattern: Circular villages develop around lakes, tanks and sometimes the village is planned in such a way that the central part remains open and is used for keeping the animals to protect them from wild animals. • Star like pattern: Where several roads converge, star shaped settlements develop by the houses built along the roads. • T-shaped, Y-shaped, Cross-shaped or cruciform settlements: T –shaped settlements develop at tri-junctions of the roads while –shaped settlements emerge as the places where two roads converge on the third one and houses are built along these roads. Cruciform settlements develop on the cross-roads and houses extend in all the four direction. • Double village: These settlements extend on both sides of a river where there is a bridge or a ferry.

    The concept of Neo determinism was introduced by Griffith Taylor which emphasises the middle path or "madhyam Marg" between two ends of environmental determinism and possibilism. The concept envisages that there is nothing absolute whether it is an absolute necessity (i.e environmental determinism) and absolute freedom (i.e possibilism)

    Griffith Taylor gave the concept of neo- determinism . According to this concept neither there is situation of absolute necessity nor is the situation of absolute freedom. We can develop also by obeying the nature.

    Factors affecting the population distribution are as under: 1. Geographic factor: (a) AVAILABILITY OF WATER- People prefer area where fresh water is available for the daily needs. Water is a necessity of life without it we cannot sustain. (b) LANDFORMS- people prefer to live on flat land or gentle scope because these areas are idle for infrastructural development and facilitate develop all around. So these areas are highly populated . In contrast, mountainous areas are less populated because these areas are hindrance in growth and development of infrastructure and other facilities. (c) CLIMATE - Areas with pleasant climate are mostly preferred because areas of harsh climate like , too hot or too cold are unsuitable for human being. Thus, the Mediterranean area and north west India are mostly preferred. (d) Soil- Areas with loamy alluvial soil are suited for agriculture and allied activities and thus they are highly populated. For e.g. ganga valley in northern India are highly populated. 2. Economics factor: (a) MINERALS- Areas rich in minerals deposits are highly populated because these mineral attract industries. (b)INDUSTRIALISATION- Industrialisation attract many people because industries create job opportunities and this are higher in population. (c) URBANISATION- People prefer to live in urbanized areas because these areas provide varied facilities to make human living ease. 3. Cultural and political factor- People prefer to live in areas where there is situation of peace and development . Because political instability and cultural turmoil affects the human development and affect the quality of life.
