This study was realized within the Project Nr. NR 8480-3 funded by the Czech Ministry of Health
- Construction of Socio-economic Deprivation Indices for Analysis of Routinely Collected data
on Health Status of Population with the Possibility of Using the GIS
Final set of factors for the construction of index:
Material factors - ownership of accommodation (including
recreational), car, phone and density of housing;
Social factors - proportion of basic education, unemployed
and singles (men, women).
Two methods were used for creating the deprivation index
based on:
1/ Townsend index that was calculated as a sum of Z-scores
of specific factors (INDEX1).
2/ MATDEP and SOCDEP that use standardized score
(INDEX2).
Methods for analysis and presentation of data:
• Pearsons correlation coefficient was applied for analysis
of relationship between indices.
• Software Stata v. 9
• The GIS (Geographical Information System – software
ArcView v. 9.0) was used for presentation of enumeration
districts deprivation.
The deprivation indices were firstly constructed on the
Moravian region census enumeration districts level.

INDEX1
Z-score is based on individual observations (X), arithmetic mean of all
observations (X) and standard deviation (s). The calculation of Zscore is based on formula
XX
Z
s
and creation of INDEX1 is based on formula:
INDEX 1 
MF1  65.78 17.88  MF2 MF3  49.67 MF4  24.91 MF5  82.95

Positive/negative value of Z-score indicates that the observation is
higher/lower than average value.
INDEX1 measures both affluence and deprivation.
INDEX2
This index was constructed using method MATDEP and SOCDEP
index. The values of specific factors for each enumeration district
were divided by maximum value of all ED for specific factor. INDEX2
was prepared separately for material deprivation (INDEX2mat)

These sub-indices were based on corresponding material and social
factors. The resulting INDEX2 was sum of these two sub-indices.

Relationship between INDEX1 and INDEX2
Regression and correlation analysis was used for the analysis of
relationship between indices. Correlation was high, especially
between INDEX1 and INDEX2 (r = 0.95)

Verification of indices
The Moravian region is determined by the districts: Bruntal,
Frydek-Mistek, Novy Jicin, Karvina, Opava, Ostrava and Karvina 6.9% of the territory of the Czech Republic
Districts
Bruntál, Karvina, Ostrava
Novy Jicin, Frydek-Mistek, Opava
Bruntal – isolated mountain area
Ostrava and Karvina - slow-down
in coal mining and heavy industry
Frydek-Místek - rapid progress
in building of new housing
Opava and Novy Jicin – the best
situation

Conclusion
• Analysis of indices' values of the Moravian districts
showed that these indices were able to give the real
information of the study areas' socio-economic
deprivation. Of course the indices have some limitations.
The most serious is actuality of indices in the period
beetween census.
• Correlation between both indices was high (r = 0.95).
INDEX1 provides the information on level of deprivation
in more detail.
• In the next phases both indices (INDEX1, INDEX2) and
two their sub-indices (INDEX2mat, INDEX2soc) were
calculated on the all districts of the Czech Republic and
used for analysis of association between socioeconomic deprivation and selected health indicators.
