Data source(s) used: Marriages: The survey on marriages, was established in 1926. It's an individual and exhaustive survey, which collects the data of all the marriages celebrated in Italy and the socio-demographic characteristics of the spouses.The survey uses the Istat D.3 model, compiled by the officer of the municipality where the marriage was celebrated. The model is divided into two parts: the first one collects the information about the marriage: the date, the rite of celebration (religious or civil), and the common property regime chosen by the couple (joint or separated ownership of property); the second one collects information about the spouses: date of birth, place of birth, place of residence at the time of marriage, future place of residence of the spouses, marital status, level of education, occupational status, position in the profession, branch of economic activity, citizenship. Other data characteristics: The indicators that do not involve the use of the population (civil weddings - percentage values, joint ownership of property - percentages, marriages with at least one foreign spouse - percentages, second or later marriages - percentages) were calculated according to three different territorial classification:- According to the classification in force in 2017 (107 provinces);- According to the classification in force at the time of the Census of 2011 (110 provinces);- According to the classification in force in the year in which the marriage was celebrated, in the event that was different from that of 2017 and of the Census of 2011 (103 provinces for 2004 and 2005, 107 provinces for the years ranging from 2006 to 2009).

Data source(s) used: Data were drawn August 31, 2011Gross contractual wages, length of work contract and yearly wages and salaries on an accrual basis: Statistics from this survey are based on concept of labour price. For each nation-wide collective agreement, the number of employees and their composition by specific wage level (combined with indications for seniority, skill, estimation about shift work) are fixed at a base year and remain constant until the renewal of base has been done. Employees exclude apprentices and managers. The base used now is December 2010=100 Moreover, these indicators are not influenced by changes due to overtime, worked hours or not worked for strikes or worker's illness. Istat produces two type of statistics on wages according to collective agreements: monthly index (IRC) and annual figures (RCA). Both indicators include basic pay, seniority and shift work allowance, all bonuses specified in national agreements and payable to all workers as well as those paid periodically (e.g. the 13th month). Bonuses related to individual performance or individual working conditions, supplementary payment agreed at the company or local level are not included. Monthly index excludes also bonuses-arrears and una tantum paid in late, but these two items are included in the annual wage figures (retribuzione annua di competenza o di cassa). Wages include tax and social security contributions paid by employees. The monthly index is calculated dividing by 12 the annual figures for each group of qualifications in the collective agreement. It shows the evolution of full-time employees' wages according to collective agreement and to law in force. General index is calculated each month as the average of the increase sets in each collective agreement signed in the national territory. The figures are derived from a selection of the most relevant nation-wide collective bargaining agreements on wages between labour unions and employers' associations. Every month the press release "Contratti collettivi e retribuzioni contrattuali" publishes two wage indices in national labour agreements: per capita and per hour. Per capita index measures the change in the collectively agreed annual wages compared to the base year. Hourly index measures the change of the wages per unit of time (annual earnings divided by the total number of working hours in the year). Annual figures are in terms of accrual or cash values. The first one (retribuzione contrattuale annua di competenza) is the annual wage amount that employees would earn each year if the National Collective Agreement came in force on time. This remuneration assigns backdated una tantum and arrears payments to the theoretical relative month. The second one (retribuzione contrattuale annua di cassa) is the sum of wages that employees have actually received every month. Accrual values are revised if the renewed collective agreement settles the payment of una tantum and/or arrears for the period in which the collective agreement is expired and the new isn't still signed.
