Not all territories start from the same conditions. ISTAT measures the vulnerability of Italian municipalities with a composite fragility index combining social, economic and environmental dimensions: from the employment rate to education levels, from access to essential services to exposure to hydrogeological risk.
The index is expressed in deciles, from 1 to 10: the higher the value, the more fragile the municipality. In this analysis we look at the data for 7,889 Italian municipalities, then drill into the individual components: employment, education and landslide risk.

ISTAT composite fragility index in deciles: 10 indicates maximum fragility
Where fragility concentrates
The municipalities reaching the maximum decile, 10 out of 10, are almost always small mountain or inner-area towns: Parzanica in the province of Bergamo, Fosciandora in the Garfagnana, Saint-Oyen and Bionaz in the Aosta Valley, Trezzone and Cavargna on Lake Como, Savogna in Friuli. Tiny communities where depopulation, ageing, scarce work and difficult terrain add up.
It is a geography that surprises those who associate fragility only with the South: the index captures a structural weakness running across the entire Alpine and Apennine arc. Italian fragility is first of all the fragility of inner areas, at any latitude.

The 10 municipalities with the lowest employment rate
Municipal employment rate: the lowest values in Italy
Employment: a 50-point gap between extremes
The heaviest component of fragility is work. In Giffone, in the province of Reggio Calabria, just 34.96 percent of the working-age population is employed; similar values in Casalattico in the Frosinone area with 35.22 percent, in Gurro in Verbano-Cusio-Ossola with 35.56 and in Francofonte near Syracuse with 37.52.
At the opposite extreme, small municipalities such as Fascia in the province of Genoa reach 86.21 percent, Ceresole Reale near Turin 85.87 and Pedesina in Valtellina 85.71. Between the municipality with the most employed and the one with the fewest there is a gap of more than 50 percentage points: two labour-market Italies coexisting in the same country. Beware of small numbers though: in municipalities with a few dozen working-age residents, a handful of jobs either way moves the percentage a lot.

Education: where qualifications remain a mirage
The second component is human capital. In Val Rezzo, in the province of Como, 78.89 percent of the population has a low level of education; Pagnona in the Lecco area follows with 74.52 percent and Mogorella in the province of Oristano with 72.17. The ranking also features Nardodipace in Calabria and Castelmagno in the Cuneo area.
Here too the common thread is not the South but marginality: small mountain municipalities where the more educated generations emigrated decades ago, leaving an elderly population that went to school in another era. Low education, in these territories, is both cause and effect of depopulation.
The 10 municipalities most exposed to landslide risk
Percentage of resident population in landslide-risk areas
Landslide risk: the Aosta Valley dominates the ranking
The third dimension is environmental. In Pontboset, in the Aosta Valley, 98.63 percent of the population lives in areas classified as landslide-prone: practically the whole village. The top of the ranking is an Aosta Valley mosaic: Rhêmes-Saint-Georges with 97.44 percent, Oyace with 96.34, Issime with 96, and even Courmayeur, the iconic Alpine tourism resort, appears.
The figure does not mean a landslide is imminent, but measures how much of the population lives in zones mapped as hazardous by hydrogeological planning. In narrow, steep valleys there is simply nowhere else to build.
Why this data matters
The fragility index is not a statistical exercise: it is the tool that can guide policies for inner areas, from local healthcare to broadband, from mountain schools to hydrogeological prevention. Knowing municipality by municipality where vulnerabilities concentrate is the first step towards not leaving the weakest territories behind.
