Cllr Barry Rawlings, Leader of Barnet Council, said:
“Accurate Census data is really important to the residents and businesses of Barnet because it helps determine government funding for our council’s services. We are reviewing the data to understand what impact it will have on service provision across the council, from adults’ social care to children’s services to businesses and environmental services, as well as the impact on our partners such as health.
“The accuracy of the data may have been affected by the Census taking place during the pandemic, and this is a big concern for us as we don’t want Barnet to lose out.
“We will look at how data can help us estimate local population growth over the next few years to ensure that we have prepared and planned to reflect the needs of the changing profile of our residents now and for the future.”
