an investigation on the Island of
Sardinia, Italy
Motivations
• Many definitions of rurality
• Connection between accessibility and rurality
A. De Montis
S. Caschili
D. Trogu
• Rurality is associated with remoteness
• Measures of rurality are powerful tools for policy-making
Rurality measures
Rurality is approached in many studies. It is defined in a variety of ways:
• Threshold census measures
A. De Montis
S. Caschili
D. Trogu
• Threshold census measures
• Continuous measures
Rural Local Units Remoteness Index (RLURI)
• Qualitative, discrete
• Population density, number of inhabitants, remoteness (isochrones)
A. De Montis
S. Caschili
D. Trogu
• Combination between the level of rurality and remoteness
• Eight classes
Rural-Urban Index (RUI)
• Composite, continuous
• Socio-economics
• Factor analysis
A. De Montis
S. Caschili
D. Trogu
• Range: 26.77 (rural)-13,988 (urban)
• 8.75% urban municipalities
Index of Relative Rurality (IRR)
• Composite, continuous
• Socio-economics, remoteness
• Standardization,
A. De Montis

D. Trogu
• Standardization, Unweighted means
• Range: 0 (urban) to 1 (rural)
• 82% under 0.50
Rural Metropolitan Interface Lebel (RMIL)
• Qualitative, discrete
• IRR, proximity to metropolitan area, population
A. De Montis
S. Caschili
D. Trogu
• Classes from A to H
• 353 up to 377 municipalities below to class G (rural-remote municipality)
Index of Multiple Deprivation (IMD)
• Composite, continuous
• Socio-economics, environmental data
• Aggregation function
A. De Montis
S. Caschili
D. Trogu
• Aggregation function
• Range: 0 to 1000
• 34,8% of municipalities lie on 200-300 interval
Comments
Comparing the indices: ranking according to the quantitative indicators.
Cagliari, Sassari, and Quartu Sant’Elena, the most populated and richest towns in Sardinia, are included in the top ten places.

Conclusion
• Sardinia would have been defined a rural region
• Quantitative rural indices are uncorrelated
A. De Montis
S. Caschili
D. Trogu
• Degree of rurality depends on the specific index variables
• In general, the higher the rurality, the lower the income and the lower the accessibility.
Outlook
• Public investments in rural areas
• Investigation on evolution of rurality
• New index to take into account factors and

• New index to take into account factors and feature of landscape and urban settings.
