联合国2005年发布的全球不平等数据库,囊括了几乎所有国家近几十年来不平等状况的发展指标。每个指标均有相应的出处。以下是该数据库的变量列表。
List of Variables
• Country3 = 3-digit country code.
• Country = country or area.
• Year (note that for a few observations for Estonia and Spain there are several
quarterly observations for the same year, denoted in Survey/Source2 as
Q1/Q2…)
• Gini coefficient in percentage points as calculated by WIDER. If deciles or
quintiles were not available this will be equal to the reported Gini.
• Reported Gini = the Gini as reported by the source (if no Gini were reported
by the source, this will include the Gini as calculated by WIDER or Deininger
& Squire for the old databases using POVCAL, a program estimating the Gini
coefficient using parametric extrapolation).
• Mean X/Y = survey mean given with the same underlying definitions as the
Gini coefficient and the share data.
• Median X/Y = survey median given with the same underlying definitions as
the Gini coefficient and the share data.
• Cur/ref = Gives the currency and the reference period for the means and
medians. If the reference is US$90/month, it means that the currency is the
1990 US dollar per month. If the reference is US/month it means that the
estimate is given in nominal value.
• Q1-Q5, D1-D10, P5, P95 = quintile, decile, percentile group shares.
• AreaCovr = area coverage. The land area which was included in the original
sample surveys etc.
• PopCovr = population coverage. The population covered in the sample
surveys in the land area (all, rural, urban etc) which was included.
• AgeCovr = age coverage. Age limits imposed on the sample population. This
is not explicitly given e.g. for the wage earning population, which by
definition excludes children and most elderly people, unless special
restrictions are used in the sample.
• IncSharU = income sharing unit/statistical unit. This variable is
corresponding to the variable sample unit in WIID1.
• UofAnala = unit of analysis, indicates wether the data has been weighted with
a person or a household weight. This variable is corresponding to the variable
enumeration unit in WIID1.
• Equivsc = equivalence scale used. This variable is corresponding to the
variable reference unit in the old database.
• IncDefn = income/expenditure definition.
• Source1 = the source from which the observation value was obtained.
• Survey/Source2 = if the survey underlying the estimates is known this
variable includes the name of the survey, otherwise it includes the source that
Source1 cites as the (primary) source.
• Quality = quality classification.
