Are More People Better for the Economy?

Pardcast: Is having less people bad for the economy or for a countrynd, why? And is it the opposite, true, that more people are instead better for the economy? On one hand, more people min more competition for work and a more hungry marchto sustain. While on the otherhand, more people means also more demand, more supply and increased under living. So which one is right? Is there an optimate number of people? And if so, what is it? And a so what is the last consensus among economists? What does the theory say, and what do the doctors say, if anything? Thank you.
