Graphed out, it shows the growth rate is increasing by more than previous years.
City of Ballarat chief executive Evan King said the data was consistent with council's forecasts, and will help more accurately steer advocacy and investment.
"There's not a department in council that doesn't use this data, (or a department where) this data doesn't impact on what they do, whether it's maternal and child health, libraries, sport and recreation facilities, roads, you name it," he said.
"It's not just about population in the end, it gives us great insights into the demographics of that population - an understanding of different age groups, how many vehicles per dwelling, there's a whole range there that helps us, from an infrastructure and social planning perspective."
Committee for Ballarat chief executive Michael Poulton said there were some positive inferences that could be drawn from the data, such as the increase in weekly household income, but the rapid growth meant there must be careful planning.
"There's a great news story in that young people and young families are coming to Ballarat to settle, that speaks volumes to the quality of life that Ballarat offers," he said.
"We've got a very liveable region, people with good jobs are coming to live here where there are good jobs available, and the type of jobs we're attracting are well-paid, and that's a very pleasing thing form a regional perspective.
"What's the greatest threat to Ballarat with growth? Liveability - it's our way of life, it's housing, transport, water infrastructure, energy, all of those things are going to impact on our liveability, (and) the real underpinning feature of that growth level is the planning implications, and that directly impacts our liveability"
