In 1970, interest on the debt was 4.3% of the Italian state’s spending; between 1993 and 1996, about 28%. What happened in between, and where does the state’s money go today, sector by sector?
To answer, I put together three series of official data on the Italian state’s spending by sector. A series records the same measure year after year; these cover different periods, include different things and cannot be joined into one. Alongside the numbers I set the historical facts that the sources document, in nine steps: from the change of currency to the limits of the numbers.
How do you compare fifty years of spending, across lire and euros?
Until 2001, the state’s accounts were in lire. The official series have already converted them into euros at the fixed rate of 1,936.27 lire to the euro: the unit changes, not the purchasing power. That is why I use percentages here, which do not depend on the currency: of every hundred euros the state spends in a year, how many go to each sector.
The total on which I calculate the percentages is final spending: everything the state spends, without the repayment of government bonds (the loans the state takes from people who buy Italian government bonds such as BOT and BTP) that come due, which is not a spending choice. Interest on the debt, instead, is real spending and stays a sector of its own.
A single homogeneous series from 1970 to 2027 does not exist. There are three series, and each measures something different:
| Series | What it measures | Years |
|---|---|---|
| State budget by functional category, that is, by purpose, such as defense or education (RGS, the State General Accounting Office, Ragioneria generale dello Stato) | the state’s payments: the money that actually went out | 1970-2009 |
| Budget law by mission, that is, by major purpose (RGS) | the state’s initial appropriations: how much the law authorizes spending at the start of the year | 2008-2027 |
| Spending of all levels of general government by function (Istat and Eurostat, COFOG classification, that is, the international classification of the functions of general government) | the spending of the state, regions, municipalities and social security institutions together | 1995-2024 |
The three series are not joined. In 2008 and 2009 the first two overlap and give different levels: in the second, for example, general administration weighs about 7.5-7.7 percentage points more (percentage points: the distance between two percentages; from 10% to 12% is 2 points). So levels before and after 2008 are not compared; trends within each series, yes.
2027 is the second year of the 2026-2028 multiyear budget, already approved (not a proposal).
Of every hundred euros the state spends, where do they go?
Of every hundred euros of final state spending in 2025, according to the budget law, the biggest sector is social spending (pensions, assistance and labor): 23.1 euros.
| Sector | Of every hundred euros, 2025 (budget law) |
|---|---|
| Social (pensions, assistance, labor) | 23.1 |
| Local and regional authorities (transfers to regions and local governments, of which about 89 billion euros for health care) | 16.2 |
| Interventions in the economy | 13.6 |
| Interest on the debt | 11.7 |
| Tax refunds and accounting adjustments | 11.2 |
| General administration (constitutional bodies, institutional services, economic and financial policies) | 9.0 |
| Education, universities, culture, research | 8.4 |
| Defense | 4.0 |
| Justice and public order | 2.7 |
| Housing and urban planning | 0.1 |
The column adds up to 100, apart from rounding. Source: RGS, OpenBDAP (initial appropriations for 2025).
In 1970 the classification was different: the numbers for the sectors that follow (interest, defense, education) are those of the state budget of the time, and should not be read as the same series.
Within the same series, the budget laws, the social sector goes from 18.5% in 2008 to 23.1% in 2025; local and regional authorities from 21.3% to 16.2%; justice and public order from 3.1% to 2.7%. Here the state’s financing of health care is not in the social sector but in local and regional authorities (88.7 billion euros in 2025, 9.7% of final spending); in the COFOG classification, further down, health is separate.
How much does interest on the debt weigh?
Interest on the debt is the most solid result of the whole analysis, in terms of direction. In 1970 it was 4.3% of state spending; between 1993 and 1996 about 28%, more than one euro in four (RGS, payments, excluding the repayment of loans). As a share of GDP, the value of what Italy produces in a year, it went from 0.8% to the 10.9% of 1993. The highest value of the share, the 30.4% of 1997, falls in a year in which the classification changes: the method note explains why it is not the true peak.

In the budget laws the share starts at 14.9% in 2008 and reaches a peak of 16.6% in 2012. Then it falls to a low of 9.4% in 2023 and rises again: 11.7% in 2025 and 12.5% in 2027.
On the debt and on interest I also wrote in “Italy’s Public Debt, Interest and Health Care: A Video’s Numbers, Checked”.
What was happening in those years, according to the sources. The sources document these facts; they do not say how much each one weighs on the share of interest.
- The 1970s. On October 17, 1973, OAPEC, the organization of the Arab oil-producing countries, decided to cut oil production, the CIA wrote in a memo of October 19: it was the first oil shock. According to the Bank of Italy (Quaderni di Storia Economica), the impact on Italy was “about twice the OECD average” (the OECD is the organization of the most industrialized countries). In those years the state’s deficit was partly financed by the Bank of Italy, which bought the bonds left unsold: a Bank of Italy study (Questioni di economia e finanza) writes, in its abstract, that in the early 1970s budget deficits and the creation of monetary base “were correlated.”
- 1981-1993. In 1981 the Treasury and the Bank of Italy began the “divorce”: the Bank was no longer obliged to buy the unsold bonds (Bank of Italy, 2011). According to the same source, real interest rates turned positive again, but “the effects of the ‘divorce’ on fiscal policy are not, however, those that were hoped for”; in the Governor’s Concluding Remarks on 1990 (May 31, 1991) we read that “Italy’s net foreign debt and the State’s debt feed a growing expenditure on interest.”
- After 1993. The fall in nominal interest rates contributed “to a considerable extent” to the reduction of the deficit in the 1990s (Bank of Italy, Annual Report on 1999); in May 1998 Italy was admitted to the euro (decision 98/317/EC). Interest rates are not in this article’s data: the link with the share of interest is a reading, not a measurement.
- 2011-2012. In the crisis of the spread (the difference in yield between Italian and German government bonds), the Bank of Italy (Annual Report on 2012) records that in 2012 interest spending by general government rose by 10.7%; the 16.6% peak in the budget laws falls in 2012.
What happened to defense?
In state spending, defense is worth:
- 1970: 10.0%.
- 1980: 4.1%.
- From 1980 to 2009: between 3.0% (1999) and 4.9% (2004).
- Budget laws 2008-2027: between 3.7% and 4.4%.
The two series agree in 2008 and 2009.
The fall as a share of GDP is smaller: from 1.95% to 1.21% between 1970 and 1980. In the 1970s the share falls partly because the rest of spending grows and partly because defense also falls as a share of GDP. For all levels of general government, defense stays between 2.2% and 2.9% of total spending from 1995 on.
Why the share of defense falls between 1973 and 1978, the sources I read do not document.
Was education cut in the 1970s?
The share of education, culture and research in state spending:
- 1970: 19.8%.
- 1980: 12.8%.
- Low: 9.1%, in 1987.
But as a share of GDP, between 1970 and 1980, it stays almost flat: from 3.9% to 3.8%.
So in 1970-1980 it is not a cut: it is the rest of spending that grows. The state’s final spending goes from 19.6% to 29.8% of GDP, and the share of each sector shrinks if the total expands.
In the budget laws the share falls from 10.7% in 2008 to 8.4% in 2025. For all levels of general government, from 1995 to 2024, education goes from 8.5% to 8.0%, with a peak of 9.7% in 2003 and a low of 7.3% in 2022.
In 2008, decree-law 112 (article 64) reduces school staff. The Bank of Italy estimates that “about 70 percent of the reduction in the number of people employed” in the public sector, from the 2006 peak, is due to schools (Annual Report on 2012, based on data from the State General Accounting Office’s annual account up to 2011). The data say that the share falls after 2008, not how much of that fall depends on this decree.
Where does the money of all levels of general government go?
The most solid figures for “where public money goes,” from 1995, come from Istat’s COFOG classification (the international classification of the functions of general government), which covers all levels of general government, not only the state.

- Social protection (pensions, unemployment, family support and assistance): from 34.0% of spending in 1995 to 42.2% in 2024, with a peak of 44.0% in 2020.
- Health: from 9.9% in 1995 to a peak of 14.8% in 2010; then it falls to 12.2% in 2023 and in 2024 it is at 13.2%.
- Education: from 8.5% in 1995 to a peak of 9.7% in 2003, then to 7.3% in 2022 and to 8.0% in 2024.
- Defense: between 2.2% and 2.9%.
- Housing and community amenities: a peak of 8.3% in 2023, against 1.0% in 2020 and 1.5% in 2024. The data do not say why.
The shares always add up to 100: in the years when housing rises to 8.3% the other functions weigh less, and in 2024, when housing returns to 1.5%, they rise again.
What do budget laws not tell?
The budget law is the spending program at the start of the year; crises decided during the year are not in it. In 2020, the year of the pandemic, the share of interventions in the economy rises by 11.6 percentage points between the budget law and the revised appropriations, that is, the amounts after changes made during the year: the initial budget law does not contain the spending decided during the year.
Two other things are not obvious. In the budget laws one euro in nine is a tax refund or an accounting adjustment: 102.6 billion euros in 2025, 11.2% of final spending, in the program “Regolazioni contabili, restituzioni e rimborsi d’imposte” (“accounting adjustments, restitutions and tax refunds”; a program is a spending item within a mission).
They are not spending for a sector, and if they stay in “general administration,” that sector looks much bigger than it is: that is why I keep them separate.
The program that has grown the most is called “interventi di sostegno tramite il sistema della fiscalità” (“support interventions through the tax system”): from 18.4 billion euros in 2019 to 61.4 in 2025. What it contains is not verified here.
It is the main part of the increase in interventions in the economy in the budget laws: from 5.2% of spending in 2008 to 13.6% in 2025, that is, 96 billion euros more, of which 61 in this program. In the multiyear budget the share returns to 11.6% in 2027.
What do the numbers say, taken together?
Lined up, the data say things that headlines about “cuts” and “waste” leave separate:
- The most marked change among those that can be read is that of interest: from 4.3% (1970) to about 28% (1993-1996) of state spending. In the budget laws, from 2008, it goes from a peak of 16.6% (2012) to a low of 9.4% (2023), then rises again.
- A share that falls is not always a cut: in the 1970s education loses share but as a share of GDP stays flat, and defense loses share and as a share of GDP falls less than the share.
- For all levels of general government the biggest weight is social protection: 42.2% of spending in 2024, rising since 1995.
- Budget laws are not all of spending: crises decided during the year, like 2020, are not in them.
What can’t the numbers say?
Two limits, to keep in mind.
- The three series. They are not joined: the first measures payments, the second initial appropriations, the third the spending of all levels of general government. Levels before and after 2008 are not compared, and 2027 is the second year of the multiyear budget, not the draft budget bill.
- The reasons. A number says how much, not why. The historical facts mentioned are those the sources document; for defense, for 2014-2027 and for the abrupt changes of 1993, 1997 and 2001, which are probably items that changed category, here I give no reasons.
All that remains is to see whether the breakdown by sector of the 2027 draft budget bill, presented to the Chamber of Deputies on October 30, 2026 (A.C. 3174), will follow that of the multiyear budget already approved.
Frequently asked questions
Why are the data in percentages and not in euros?
Because until 2001 the accounts were in lire. The official series convert them into euros at the fixed rate of 1,936.27 lire to the euro: the unit changes, not the purchasing power. Percentages say, of every hundred euros the state spends in a year, how many go to each sector, and they do not depend on the currency.
What is interest on the debt?
It is what the state pays every year to those who lent money by buying its bonds. In 1970 it was 4.3% of state spending and between 1993 and 1996 about 28% (payments, RGS); in the multiyear budget, 2027 is at 12.5%.
Has defense spending fallen?
Yes, as a share: from 10.0% of state spending in 1970 to 4.1% in 1980, then between 3.0% and 4.9%. As a share of GDP the fall is smaller, from 1.95% to 1.21% between 1970 and 1980. In the 1970s the share falls partly because the rest of spending grows and partly because defense also falls as a share of GDP.
Where does the money of all levels of general government go in 2024?
In 2024, according to Istat, 42.2% of total spending goes to social protection (pensions, unemployment, family support and assistance), 13.2% to health, 8.0% to education and 2.6% to defense. These are shares of the spending of the state, regions, municipalities and social security institutions together.
Why isn’t there a single series from 1970 to 2027?
Because the official sources change and measure different things: state payments through 2009, initial appropriations of the budget laws from 2008. In 2008 and 2009 they overlap with different levels: trends within each series are compared, not levels between series.
Is 2027 the draft budget bill?
No: the 2027 data are those of the 2026-2028 multiyear budget, already approved. The draft bill for 2027, the government’s proposal that Parliament must approve, is not among the data used.
Download the data and the code
I have gathered in a zip file the tables and the code with which I redid the calculations, so that anyone who wants to can repeat the analyses. Inside are the processed tables in CSV files, that is, plain-text tables (the three series, the comparison between the series and between initial and revised appropriations), the scripts that redo the calculations and draw the three charts, written in R, a language for data analysis, a file of instructions and the list of downloaded files, with address, date and fingerprint. The original data from RGS, Eurostat and AMECO are not in the file: they can be downloaded from the sites listed in the sources.

Method note (for those who want to check the math)
The shares for the state (1970-2009 and 2008-2027) are calculated on final spending, that is, the total without the repayment of loans. For the budget laws I grouped the missions into sectors: for example, defense includes defense and civil rescue, as the RGS did with civil protection; tax refunds and accounting adjustments and the financial relations with local and regional authorities are sectors of their own; interest is macro-aggregate 7 “oneri del debito pubblico” (“public debt charges”) in any mission. The share of GDP uses AMECO’s nominal GDP, with the same conversion of the lire; for 2026 and 2027 there is none, because GDP is only forecast.
I checked the series against one another. For interest, defense, education, justice and social spending, the changes in 1995-2009 (for interest, 2001-2009) in the payments series and those in the COFOG data for central government go in the same direction (correlations of the levels between 0.56 and 0.90); for interventions in the economy they do not, and that is why I do not discuss them. Initial and revised appropriations in the 2008-2025 budget laws differ by less than one point on average, with the exception of 2020 (11.6 percentage points in interventions in the economy).
In 1997, interest in euros falls from 103.1 to 98.9 billion and as a share of GDP from 9.8% to 9.0%, while its share rises from 28.1% to 30.4%, because the final spending on which it is calculated falls from 366 to 325 billion (from 35.0% to 29.7% of GDP) and rises again in 1998-1999.
The 2027 draft budget bill (A.C. 3174, the text the government presented to the Chamber of Deputies) is not in the data: 2027 is the second year of the 2026-2028 multiyear budget. On the 2027 budget package and on energy I wrote in “Italy’s budget and energy: where the MASE’s €14 billion comes from”.
In the payments series the classification changes in 1998, and in some years (1993, 1997, 2001) there are jumps in opposite directions, probably items that changed category and not spending that changed (for 2001, from 2001 the health care of the ordinary-statute regions is no longer financed with transfers from the state: legislative decree 56/2000): that is why I do not discuss them and draw no conclusion on the weight of interventions in the economy before 2009.
In the COFOG series, interest on the debt is separated only from 2001, and 2025 has not yet been published by Eurostat.
On housing: Istat, in its press release of March 1, 2023, writes that, after further examination with Eurostat, the tax credits of the Superbonus and of the Bonus facciate (the facade bonus) are classified as “payable” (credits that, with reasonable certainty, will be used in full over time) and recorded as expenditure for the full amount, from 2020; whether the housing peak depends on this, the COFOG data do not say.
The data were downloaded on November 4, 2026. The R code and the tables are in the zip file attached to this article; the original files can be downloaded again from the sources with the 00_scarica_fonti.R script, which is in the zip.
