Italy's National Institute of Statistics: Reorganization and Collaboration in 1926

The institutional origins of Italy's National Institute of Statistics (ISTAT) lie in Law No. 1162 of July 9, 1926, reorganizing statistical services. Then called the Central Institute of Statistics of the Kingdom of Italy, the new institution took over the functions of the Directorate-General of Statistics, previously within the Ministry of National Economy. The law granted it legal personality and operational autonomy while placing it directly under the head of government, Mussolini.

The law appeared in the official gazette on July 14, and Article 19 stipulated that it would enter into force on the thirtieth day after publication. The legislative date, publication date, and entry into force were therefore not identical. The significance of 1926 was the reorganization of national statistical institutions, not the first collection of statistics in Italy.

The new institute inherited the use of the former directorate's premises, along with its machinery, furniture, and library. The state allocated two million lire annually for its first two years; sales of publications and reimbursement for commissioned work provided additional income. The law required it to produce a statistical yearbook and bulletins and coordinate surveys by administrative bodies. It could also promote statistical research through scholarships and awards.

Corrado Gini was first appointed president of the Supreme Council of Statistics. The appointment decree of October 27, 1926, listed scholars including Luigi Amoroso and Rodolfo Benini of the University of Rome, Livio Livi, and Franco Savorgnan, as well as representatives of immigration, railways, customs, and Fascist industrial, agricultural, and corporative organizations. The council thus connected researchers, holders of administrative data, and interest groups recognized by the regime.

Giovanni Favero's institutional history notes that the initial reform allowed administrative departments to retain their statistical services while the central institution set scientific standards. This coordinating arrangement soon met resistance: departments controlling registration procedures and local operations did not automatically accept instructions from statistical experts. Gini sought to concentrate more functions in the institute, while the financial authorities constrained his personnel policies.

The 1929 reform strengthened the powers of the president and director-general, with Alberto Molinari becoming director-general. Centralization still depended on cooperation among departments and could not be achieved by decree alone. Training specialized personnel consequently became particularly important. Linking university statistical education with qualifications for administrative employment offered one route to sustaining professional expertise.

Between 1929 and 1931, Gini and the young mathematician Bruno de Finetti developed population projections. Carl Ipsen's article explains that the project combined the 1921 census, life tables, and estimates of age-specific fertility to project the population year by year, comparing scenarios in which fertility and mortality remained constant or declined.

Population registers did not record mothers' ages. Researchers therefore had to use formulas to allocate births and estimate fertility rates, followed by extensive manual calculation. The project depended on mathematical assumptions as well as administrative records. Detailed calculations could not eliminate gaps in the underlying data.

After preliminary results appeared in 1930, Livi criticized the principal scenario for excluding emigration and using an outdated base period. Luigi Galvani, from the institute's mathematics and cartography department, responded to the criticism, and revised projections incorporated migration. A meeting of the International Statistical Institute in Tokyo provided an international forum for discussing the results.

Mussolini's pronatalist policy gave the research political weight. Ipsen argues that statistical bias need not result from fabricated data; it can also arise from choices of data and assumptions that appear technically justified. The controversy demonstrates that collaboration among experts still required substantive public scrutiny.

Favero notes that after Gini's departure in 1932, management under Savorgnan and Molinari paid greater attention to routine organization and technical procedures. The institute's professional capabilities survived the change of leadership. An important consequence of the 1926 reform was therefore the creation of an organization that continuously produced data and trained technical personnel, although its operations remained constrained by budgets and political power.

Legislative Decree No. 322 of 1989 renamed the Central Institute of Statistics the National Institute of Statistics and assigned it planning, survey, and technical-coordination responsibilities within the National Statistical System. The consolidated legislation also specifies Rome as its headquarters. The later name and framework for cooperation cannot simply be projected back onto the founding year, but they show how the early task of centralizing statistical data entered a new institutional framework.
