LABOUR FORCE AND EMPLOYMENT

Populationis a total number of people residing in a particular area  at a particular point of time. Labour force is a segment of nations population. Labour refers to the people who are working or seeking a job or searching a job or both in period of time.it indicates the supply labour in the country. The relaible estimation of rural-urban, male-female labour force is important for framing policy and economic planning.

As per the labour bureau-Annual report 2011-12 "labour force participation rate" (LFPR) is defined as the number of person in the labour force per 1000 persons. It is one of the important labour force parameyers.

It can be calculated as:

LFPR= No.of employed persons+no. Of unemployment persons×1000

So it is the number of people who either emplpyed or activity searching work ( unemployed) for every 1000 persons. It depends upon age, gender, rural-urban composition of population. LFPR is an important indicator, which helps us to measure , analyse and understand the employment condition in the nation.

Workers population ratio is anthor important parameter of work force. It is defined as the number of employed persons per 1000 persons. It can be calculated as

WPR=Number of employed peesons×1000

WPR can also be calculated by deducting unemployment person from labour force paeticipation rate. This is also used ti find the number of people contributing to the production of goods and services in a countries population. If the ratio is more it indicates that more number of people are working. If the ratio is low it indicates less number of people
