The present report is a documentation of the insights related to New Towns and migration from the two-day New Town Lab in Vällingby and it should be read within that context. The lab was the fourth of five events as part of the two-year project “New Towns Arrival Cities”, led by the Municipality of Nissewaard and coordinated by INTI, the International New Town Institute. European New Towns, built by the welfare state to accommodate growing urban populations, all share a social democratic background and planned nature; today, they all face similar challenges as they struggle to adapt to rapidly growing and diversifying populations.
