The Department for Education (DfE) does not hold information on take-up of funded childcare for disadvantaged and non-disadvantaged households. However, the 2-year-old free entitlement is specifically for disadvantaged children, and take-up nationally is 71%, up 13 percentage points from 2015.
Information on take-up at constituency level is not readily available and could only be obtained at disproportionate cost.
Take-up rates for 2- and 3-year-olds by local authority are published in Table 5LA of the ‘Education Provision for Children Under 5 Years of Age’ Statistical First Release: https://www.gov.uk/government/statistics/education-provision-children-under-5-years-of-age-january-2017.
Take-up rates for 2-year-olds are calculated using the estimated number of eligible children derived from data supplied to the DfE by the Department for Work and Pensions on the number of children believed to meet the benefit and tax credit eligibility criteria. It represents the best data available on the number of eligible children in each local authority area. Take-up rates for 3-year-olds are calculated using adjusted population estimates from the Office for National Statistics (ONS).
