Given that at the beginning of 1973, Nigeria had a birth rate of 3% per annum and a population of 75 million, it means that there were 2.25 million live births in that year. Birth rate refers to the number of live births per 1000 people in a population within a specific period. Therefore, a birth rate of 3% implies that for every 1000 people in the population, 30 births occurred in a year. To calculate the number of live births in a population of 75 million with a birth rate of 3%, we can use the formula: Live births = (Birth rate/1000) x Total population Substituting the values, we have: Live births = (3/1000) x 75,000,000 = 2,250,000 Therefore, in 1973, Nigeria had 2.25 million live births.
