Is there an effect both positive or negative to the county's economy when couples have plenty children?
In the past before the current economic era, around the 15th century and the beginning of the French industrial revolution, having many children was seen as fertility and good for both the family work force and country's also. The labour force was majorly manual and those who worked at the plantations were sort after as able bodied men or women.
But at the moment, what is the viability of having many children especially as it could reduce the per capital income.
It depends on the country, some countries have strict laws on the number of children a couple is allowed to have, some are more diplomatic about it and use every medium to encourage family planning and birth control. In other countries, the government are not so concerned about the increasing population. The risk of population explosion is common in developing countries and the problem starts when the resources of the nation cannot serve the population. It’s a hard culture to break because many believe they can have as many kids as they want as long as they can take care of their needs, but on a large scale this has a ripple effect on the economy of the country. It’s not surprising that the world’s most populated nation is one of the poorest nation in the world today.
