  • Over the quarter, the increase in NI production output was driven by increases in two of the four main sectors - Manufacturing (2.2%) and Electricity, gas, steam and air conditioning supply (1.7%). This was partially offset by decreases in Water supply, sewerage and waste management (Inc. recycling) (1.4%) and Mining and quarrying (5.6%). 

  • Over the year the increase in NI production output was driven by a 3.6% increase in Manufacturing. This was offset by decreases in Electricity, gas, steam and air conditioning supply (1.1%), Water supply, sewerage and waste management (Inc. recycling) (0.4%) and Mining and quarrying (13.0%).
