Population Growth
जनसंख्या वृद्धि
In Class 9 Geography, within the chapter Population, students study population growth as the change in the number of people over time. The topic explains how birth rates, death rates, and migration influence population size, and helps learners understand why growth patterns vary across places and periods.
Practice questions
If jobs are decreasing in an area and youth are leaving, what effect can occur on future population growth?If a country's birth rate has fallen but life expectancy is increasing, what effect on population structure is possible?If population growth rate is twenty percent and previous population is seventy lakh, what will be the absolute increase?If an area's growth rate is rising but death rate is also rising, which component must be checked more to explain growth?If natural increase rate is five per thousand and net migration is minus eight per thousand, what will be total growth rate?If total population is rising but number of children per family is declining, which reason is possible?If population growth is very rapid but water and housing resources are limited, which effect is most likely?If an area has very low birth rate and high emigration, what can be a long-term concern?If an area's previous population is one hundred twenty lakh and increase is twenty four lakh, what is the growth percentage?If death rate falls after health improvement and later birth rate also falls due to education, how can the direction of growth change?If net migration is positive but housing and services are not increasing in an area, what problem will arise?If natural increase is low but total population is rising rapidly, which question should be asked?If an area's growth rate is high mainly due to immigration, what conclusion should not be drawn about birth rate?If previous population is sixteen lakh and current population is twenty four lakh, what is the growth percentage?If population growth is slow but urbanisation is rapid in an area, what should be understood?If birth rate is lower than death rate but immigration plus births exceed deaths plus emigration, what will be the total change?If an area's growth rate is continuously declining, for which long-term change should administration prepare?At expert level, what is the correct order for analysing population growth?If birth rate is falling in an area but very high immigration is increasing the working-age group, how should population growth be analysed?What is called population growth?
