The local administrative units, abbreviated as LAUs, form a system for dividing up the economic territory of the European Union (EU) for the purpose of statistics at local level. They have been set up by Eurostat and they are compatible with NUTS. The LAU classification is equivalent to the classification of all Maltese local councils into six districts by Malta Geographic Codes (MGC). At local level, two levels of LAU have been defined: the upper level (LAU1, formerly NUTS level 4) which are the six districts and the lower level (LAU2, formerly NUTS level 5) which consist of the 68 local councils.

The data on expenditure under the various social protection schemes are drawn up according to the ESSPROS (European System of integrated Social Protection Statistics) Manual issued by Eurostat. Generally, the objectives of ESSPROS are to provide a comprehensive, realistic and coherent description of social protection which: (i) covers social benefits and their financing; (ii) is geared towards international comparability; and (iii) is completely harmonised with other statistics, particularly the National Accounts, in its main concepts. The Survivors function contains the following benefits: Early Survivors Retirement Pension, National Minimum Widows Pension, Pensions of Widows with Children, Survivors Pension, Widows Pension and Orphans' Allowance. Spatial ESSPROS data is represented per 1000 population. The data source used to compile the beneficiaries data is the System for the Administration of Social Benefits (SABS) database held by the Department of Social Security. Beneficiaries are grouped according to their ID card number. If a person received a particular benefit more than once in a calendar year, the records show one beneficiary. Beneficiaries obtaining more than one benefit under the same function are counted once. Beneficiaries living abroad are not included in the data.
