The national land use tables published by MHCLG show that in 2017, 56.6% of the borough was covered by green spaces including agriculture, forest and open land, water and outdoor recreation spaces. Close to one fifth was accounted for by residential gardens. The district relies heavily on other parts of Essex including factories and ports in Tilbury, the large town of Southend-on-Sea and on Central London for its largest sources of employment and as it has areas of seaside resort the median age of residents was in 2011 greater than the national average: 7% of its residents were aged 75 to 84 compared with 5.5% nationally.
