If you mean in the US, the population of longtime people-have parents, grandparents,great grandparents- born here, the population is on a decline.
Immigration migrations bring in more people, causing for their population to go up as well as with them having children.
Other than that and in some places around the world, population is rising. We're nearing 7billion, which will grow at an exponential rate from the
years following and beyond.
Interesting read about Canada's happening in this post.
