To the west lie Ely, Caerau and Fairwater which contain some of the largest housing estates in the United Kingdom. With the exception of some of the outlying privately built estates at Michaelston-super-Ely and 1930s developments near Waun-Gron Road, this is an economically disadvantaged area with high numbers of unemployed households. Culverhouse Cross is a more affluent western area of the city. Heath, Birchgrove, Gabalfa, Mynachdy, Llandaff North, Llandaff, Llanishen, Radyr, Whitchurch & Tongwynlais, Rhiwbina, Thornhill, Lisvane and Cyncoed lie in an arc from the northwest to the northeast of the centre. Lisvane, Cyncoed, Radyr and Rhiwbina contain some of the most expensive housing in Wales.
