This isambitiousandourchartsfalla longwayshortofbeingcomplete,as is illustratedinTable1,whichshowsthedatesatwhich,foreachcountry,thefiveindicatorscommence.Inthe past, more evidence was available about the upper part of the distribution, and ourindicatorscoverthetopincomesharesmorefully.Fortheotherindicators,coverageismorelimited.Inonlyfiveofthetwentyfivecountriesdothedataonoverallinequalitystartbefore1945.Inmanycasesdataarenotalwaysavailableforeveryyearandtherearegapsintheseries. These are joined within the graphs but it is worth noting that this may well missimportantyear-to-yearvariations.Insomecases,particularlyforwealth,wehavelocatednotimeseriesatall.
Our emphasis is on change over time.We have therefore concentrated on comparabilityovertime,andforthisreasonpresentedtheevidencecountrybycountry.
Whatdotheindicatorsshow?
Foreachofthefiveindicators,wehaveapreferredorotherwisestandarddefinition,butwehavehadtodepartfromthiswherenodataareavailableonthisbasis.Toaidthereader,wehaveinthechartsmarkedbythesymbol(*)theseriesbasedonthepreferred(orstandard)definition. In a number of countries, this includes cases where data are available on thepreferreddefinitiononly for the later part of theperiod, butwherewehavenonethelesschosentopiecetogetheralongerseriesfromsourcesthatmakeuseofdifferentdefinitions.
Inthecaseofoverallincomeinequality,ourpreferredincomeconceptisequivalised(usingascale to allow for differences in household size and composition) household disposableincome,definedasincomefromallsources,includingtransferpayments,minusdirecttaxesandsocialsecuritycontributions.Theequivalencescaleusedinmostcasesisthe“modifiedOECDscale”,whichgivesaweightof1tothefirstadult,of0.5toeachadditionaladult,andof 0.3 to each child. Thismeans that the incomeof a family of 2 adults and 2 children isdivided by 2.1. In some cases, other scales are employed, such as the square root scale,where income is divided by the square root of the household size (2 in the example justgiven). Thedistribution is amongpersons: each individual appears in thedistributionwiththe equivalised income of the household. No allowance is made for within-householdinequality. Inanumberof cases, thedefinitions in theavailable statisticsdepart fromthispreferred version. For example, income may not be adjusted for household size andcomposition,orthedistributionmayrelatetogrossincome,beforethedeductionofincomeandsocialsecuritytaxes.Becausetheincometaxisusuallyprogressive,inequalityistypicallyhigherforgrossincomethanfordisposableincome.
The overall distribution is summarised in a single summary statistic, typically the Ginicoefficient, most commonly published by statistical agencies. The explanation of thecoefficientgivenbymostagenciesismadeintermsofgeometry,butweprefertodescribeitintermsofthemeandifference.AGinicoefficientofGpercentmeansthat,ifwetakeanytwohouseholds fromthepopulationat random,theexpecteddifference is2Gpercentofthemean. So that a rise in the Gini coefficient from 30 to 40 per cent implies that theexpecteddifferencehasgoneupfrom60to80percentofthemean.Anotherusefulwayofthinking, suggested by Amartya Sen, is in terms of “distributionally adjusted” nationalincome,whichwiththeGinicoefficientis(100-G)percentofnationalincome.Sothatarise

intheGinicoefficientfrom30to40percentisequivalenttoreducingnationalincomeby14percent(1/7).
Muchoftheevidenceabouttopincomesharesisderivedfromtaxrecords,andourstandard– although not necessarily preferred – definition is gross income for tax purposes beforededuction of allowable outgoings. Typically, but not exclusively, income here excludescapitalgainsandlosses.Wherebothincludingandexcludingcapitalgainsdatawasavailable(asfortheUnitedStatesandSweden)wehavechosenthelatter.Transferincomeiscoveredtovaryingdegreesindifferentcountries.Becausethetaxsystemistypicallyprogressive,thetopsharesindisposableincomearesmaller:forexample,intheUKin2000theshareofthetop1percentinbeforetaxincomewas12.7percent,whereastheshareinaftertaxincomewas 10.0 per cent. It is also worth noting that the measuring unit is typically not thehouseholdbuttheunitreportingincomefortaxpurposes(thetaxunitistypicallyformedbymarriedcouplesandunmarriedadultsoradultsonlydependingon the taxation regimeofeach country). The evidence about top shares is presented in terms of the shares of,typically,thetop1percent.Thisisreadilyinterpreted:ashareof10percentforthetop1percentmeansthattheyreceive10timestheirproportionateshareofincome.
OurpreferreddefinitionofpovertyfollowsthatadoptedintheEuropeanUnion(EU)agreedcommon social indicators: a relative measure set at 60 (or 50) per cent of the medianequivalised disposable income in the country in question. In some cases, the figurespresented relate toabsolutepovertymeasuresbasedonapoverty line fixedover time intermsofpurchasingpower. Itshouldbestressedthattherelativemeasure isnotsimplyameasureofinequality.ItwouldbequitepossiblefortheEUmeasuretobereducedtozerowithoutinequalitybeingeliminated:asituationwherenoonereceiveslessthan60percentofthemedianisquiteconsistentwithconsiderableinequality.
Our preferred definition of earnings dispersion refers to thewage and salary received bythose inemploymentandwhoseemploymentwasnotaffectedbyabsence. The indicatorusedinmostcasesistheratioofearningsatthetopdecile(theperson10percentfromthetop) to themedianearningsexpressedasapercentage. This isameasureofhow far thedistributionofearningsisspreadoutatthetop:afigureof180percentmeansthatthoseinthetop10percentofearningsreceive80percentormoreinexcessofmedianearnings.
Theindicatorofwealthistakentobethenetworthofeitherindividuals(asinestatedata)or of households (as in survey data). “Net” means that all liabilities (debts) have beensubtracted from the total assets (real and financial); the figure for some households isnegative(forexamplewherethemortgageexceedsthevalueoftheproperty).Thesummaryindicatorusedinmostcasesistheshareofthetop1percent.Afigureof25percentmeansthatthetop1percentowns25timestheirproportionateshare.
Linkingofseriesovertime
Discontinuities in statistical series on inequality are frequent. The US Census Bureau“selected measure of household income dispersion” covers the period from 1967 to thepresent, but there are no fewer than 19 footnotes indicating changes in the processingmethod.Thisismorethanoneeverythirdyear.Dealingwiththeseisamatterforjudgment.InconstructingtheseriesintheChartbook,theruleswehavefollowedare(a)toacceptin

In a few instances,where a discontinuity is present in very recent years, we have applied the proportionallinking, as described above, forward rather than backward. This avoids recentmethodologicalchangesaffectingobservationsforthedistantpastinlong-runseries.
The proportionate linkingmeans that the reader can rely on the year-to-year percentagechanges, but means that the figures graphed here may differ from those in the originalsources.

As for theWID.worlddataonTop income shares,wemostly refer todatadownloaded inDecember 2016. At the same time, it is worth stressing that not all data on top incomeshares is taken from theWID.world. This is the case, for instance, of Brazil and Iceland,whereestimatesaretakenfromexistingliterature.

What’snewinthe2017version?
Itisworthstressingthatthe2017versionoftheChartbookofEconomicInequalitycontainsimportantdifferenceswithrespecttoitsprecedingversions.Firstofall,allserieshavebeenupdated,extendingthecoverageintime,bothforwardandbackwardwheneverpossible.Second,thereliabilityofalldatahasbeenre-assessedleadingtotheomissionofafewseriespreviously included and the replacement of specific data where a more compellingsubstitute has become available or otherwise brought to our attention. In some cases,amendments have beenmade in theway different series are linked together, or links toadditionalserieshavebeenintroducedinordertoprovideamoreconsistentlong-runview.Third,alloriginalsourceshavebeenindividuallyverifiedandprovidedinaseparatesourcessheet foreachcountry, fromwhich theChartbookseriesarecalculated, soas toallow forfull replicability. This has led to some modest revisions of some Chartbook series whereroundedfigureshadbeenusedpreviously.This important additional information can now be found online which, we hope, willincreaseboththereliabilityoftheChartbookseriesandtransparencyintermsofhowtheyhave been constructed.
