            Question 1.
            \nExplain Registration method and Census method of collecting Vital Statistics.
            \nAnswer:
            \nRegistration method is the method of continuous, permanent and compulsory recording of vital events due to the Legal importance. When ever Vital events Occur in the population, are registered at the Registers of municipal offices, panchayat offices, Hospitals etc. When births are registered information of age of mother, caste, sex of a baby etc., are registered. Similarly when death occurred, information regarding sex , religion, marital status, age of death, cause of death etc., are registered.<\/p>\n

            Census method is the complete enumeration of each and every unit of the population of a particular area under study, at regular intervals. In India, once in every 10 years census is conducted. In this method information regarding birth, death, marriage, literacy etc., are collected.<\/p>\n

            \nAnswer:
            \nGiven P0<\/sub>= Population at the end of 2004 = 4,43,850.
            \nB= 10,452, D = 6,845, 1 = 44,680, E= 12,435
            \nThe estimate of the population at the end of 2005 is – .
            \nPt<\/sub>= P0<\/sub>+ (B – D) + (I – E)
            \n= 4,43,850 + (10,452 – 6,845) + (44,680 – 12,435)
            \n= 4,79,702
            \n\"2nd
            \nThe crude birth rate is –
