What Lisburn and Castlereagh actually fills in

A "field" is one piece of information on an application — the decision date, the applicant's name, the address. Councils fill these in inconsistently, so this table measures how often Lisburn and Castlereagh actually provides each one, across all 3,024 records. Anything listed as reliable you can count on; anything lower, check the council's own record before relying on it.
