The rising family size in some rich countries.

Though nuclear family is the social order across the world, in some rich countries, the average size of the family is becoming bigger-- with three, four even five children.

What all reasons do you attribute to this?

Is it a positive or negative development? 

The family order as such in some richer countries is undergoing a shift these days and,  as a result, there are families with greater number of children. I can identify several reasons for this rising size and, in my view, it is not a positive order.

The prime reason for this change of order is the rising economic well-being being experienced by the already rich families. This happens by way of greater possibilities to augment wealth. When the wealth status rises, the new families mull the need for one or two additional children to share their wealth with.

The second thing is these countries are facing extensive migration from around the world. In order to plug this exodus, social scientists, economists and even some religious heads encourage many new generation parents to have a few more children. The uncertainty over old are also can be cited as a reason for this. For example, some parents may feel that at least one of their children will be around in the evenings of their life.   

TRy ot complete the essay by adding one more paragraph addressing the second question and the reaction that it is not a positive turn of event.
