  Bythatlawofournaturewhichmakesfoodnecessarytothelifeofman,theeffectsofthesetwounequalpowersmustbekeptequal。
  Thisimpliesastrongandconstantlyoperatingcheckonpopulationfromthedifficultyofsubsistence。Thisdifficultymustfallsomewhereandmustnecessarilybeseverelyfeltbyalargeportionofmankind。

  ISAIDthatpopulation,whenunchecked,increasedinageometricalratio,andsubsistenceformaninanarithmeticalratio。
  Letusexaminewhetherthispositionbejust。Ithinkitwillbeallowed,thatnostatehashithertoexisted(atleastthatwehaveanyaccountof)wherethemannersweresopureandsimple,andthemeansofsubsistencesoabundant,thatnocheckwhateverhasexistedtoearlymarriages,amongthelowerclasses,fromafearofnotprovidingwellfortheirfamilies,oramongthehigherclasses,fromafearofloweringtheirconditioninlife。
  Consequentlyinnostatethatwehaveyetknownhasthepowerofpopulationbeenlefttoexertitselfwithperfectfreedom。

  Inastatethereforeofgreatequalityandvirtue,wherepureandsimplemannersprevailed,andwherethemeansofsubsistenceweresoabundantthatnopartofthesocietycouldhaveanyfearsaboutprovidingamplyforafamily,thepowerofpopulationbeinglefttoexertitselfunchecked,theincreaseofthehumanspecieswouldevidentlybemuchgreaterthananyincreasethathasbeenhithertoknown。
  IntheUnitedStatesofAmerica,wherethemeansofsubsistencehavebeenmoreample,themannersofthepeoplemorepure,andconsequentlythecheckstoearlymarriagesfewer,thaninanyofthemodernstatesofEurope,thepopulationhasbeenfoundtodoubleitselfintwenty—fiveyears。
  Thisratioofincrease,thoughshortoftheutmostpowerofpopulation,yetastheresultofactualexperience,wewilltakeasourrule,andsay,thatpopulation,whenunchecked,goesondoublingitselfeverytwenty—fiveyearsorincreasesinageometricalratio。
  Letusnowtakeanyspotofearth,thisIslandforinstance,andseeinwhatratiothesubsistenceitaffordscanbesupposedtoincrease。Wewillbeginwithitunderitspresentstateofcultivation。
  IfIallowthatbythebestpossiblepolicy,bybreakingupmorelandandbygreatencouragementstoagriculture,theproduceofthisIslandmaybedoubledinthefirsttwenty—fiveyears,I
  thinkitwillbeallowingasmuchasanypersoncanwelldemand。
  Inthenexttwenty—fiveyears,itisimpossibletosupposethattheproducecouldbequadrupled。Itwouldbecontrarytoallourknowledgeofthequalitiesofland。Theveryutmostthatwecanconceive,is,thattheincreaseinthesecondtwenty—fiveyearsmightequalthepresentproduce。Letusthentakethisforourrule,thoughcertainlyfarbeyondthetruth,andallowthat,bygreatexertion,thewholeproduceoftheIslandmightbeincreasedeverytwenty—fiveyears,byaquantityofsubsistenceequaltowhatitatpresentproduces。Themostenthusiasticspeculatorcannotsupposeagreaterincreasethanthis。InafewcenturiesitwouldmakeeveryacreoflandintheIslandlikeagarden。
  Yetthisratioofincreaseisevidentlyarithmetical。
  Itmaybefairlysaid,therefore,thatthemeansofsubsistenceincreaseinanarithmeticalratio。Letusnowbringtheeffectsofthesetworatiostogether。
  ThepopulationoftheIslandiscomputedtobeaboutsevenmillions,andwewillsupposethepresentproduceequaltothesupportofsuchanumber。Inthefirsttwenty—fiveyearsthepopulationwouldbefourteenmillions,andthefoodbeingalsodoubled,themeansofsubsistencewouldbeequaltothisincrease。Inthenexttwenty—fiveyearsthepopulationwouldbetwenty—eightmillions,andthemeansofsubsistenceonlyequaltothesupportoftwenty—onemillions。Inthenextperiod,thepopulationwouldbefifty—sixmillions,andthemeansofsubsistencejustsufficientforhalfthatnumber。Andattheconclusionofthefirstcenturythepopulationwouldbeonehundredandtwelvemillionsandthemeansofsubsistenceonlyequaltothesupportofthirty—fivemillions,whichwouldleaveapopulationofseventy—sevenmillionstotallyunprovidedfor。
  Agreatemigrationnecessarilyimpliesunhappinessofsomekindorotherinthecountrythatisdeserted。Forfewpersonswillleavetheirfamilies,connections,friends,andnativeland,toseekasettlementinuntriedforeignclimes,withoutsomestrongsubsistingcausesofuneasinesswheretheyare,orthehopeofsomegreatadvantagesintheplacetowhichtheyaregoing。
  Buttomaketheargumentmoregeneralandlessinterruptedbythepartialviewsofemigration,letustakethewholeearth,insteadofonespot,andsupposethattherestraintstopopulationwereuniversallyremoved。Ifthesubsistenceformanthattheearthaffordswastobeincreasedeverytwenty—fiveyearsbyaquantityequaltowhatthewholeworldatpresentproduces,thiswouldallowthepowerofproductionintheearthtobeabsolutelyunlimited,anditsratioofincreasemuchgreaterthanwecanconceivethatanypossibleexertionsofmankindcouldmakeit。
  Takingthepopulationoftheworldatanynumber,athousandmillions,forinstance,thehumanspecieswouldincreaseintheratioof——1,2,4,8,16,32,64,128,256,512,etc。andsubsistenceas——1,2,3,4,5,6,7,8,9,10,etc。Intwocenturiesandaquarter,thepopulationwouldbetothemeansofsubsistenceas512to10:inthreecenturiesas4096to13,andintwothousandyearsthedifferencewouldbealmostincalculable,thoughtheproduceinthattimewouldhaveincreasedtoanimmenseextent。
  Nolimitswhateverareplacedtotheproductionsoftheearth;theymayincreaseforeverandbegreaterthananyassignablequantity。yetstillthepowerofpopulationbeingapowerofasuperiororder,theincreaseofthehumanspeciescanonlybekeptcommensuratetotheincreaseofthemeansofsubsistencebytheconstantoperationofthestronglawofnecessityactingasacheckuponthegreaterpower。
  Theeffectsofthischeckremainnowtobeconsidered。
  Amongplantsandanimalstheviewofthesubjectissimple。
  Theyareallimpelledbyapowerfulinstincttotheincreaseoftheirspecies,andthisinstinctisinterruptedbynoreasoningordoubtsaboutprovidingfortheiroffspring。Whereverthereforethereisliberty,thepowerofincreaseisexerted,andthesuperabundanteffectsarerepressedafterwardsbywantofroomandnourishment,whichiscommontoanimalsandplants,andamonganimalsbybecomingthepreyofothers。
  Theeffectsofthischeckonmanaremorecomplicated。
  Impelledtotheincreaseofhisspeciesbyanequallypowerfulinstinct,reasoninterruptshiscareerandaskshimwhetherhemaynotbringbeingsintotheworldforwhomhecannotprovidethemeansofsubsistence。Inastateofequality,thiswouldbethesimplequestion。Inthepresentstateofsociety,otherconsiderationsoccur。Willhenotlowerhisrankinlife?Willhenotsubjecthimselftogreaterdifficultiesthanheatpresentfeels?Willhenotbeobligedtolabourharder?andifhehasalargefamily,willhisutmostexertionsenablehimtosupportthem?Mayhenotseehisoffspringinragsandmisery,andclamouringforbreadthathecannotgivethem?Andmayhenotbereducedtothegratingnecessityofforfeitinghisindependence,andofbeingobligedtothesparinghandofcharityforsupport?
  Theseconsiderationsarecalculatedtoprevent,andcertainlydoprevent,averygreatnumberinallcivilizednationsfrompursuingthedictateofnatureinanearlyattachmenttoonewoman。Andthisrestraintalmostnecessarily,thoughnotabsolutelyso,producesvice。Yetinallsocieties,eventhosethataremostvicious,thetendencytoavirtuousattachmentissostrongthatthereisaconstantefforttowardsanincreaseofpopulation。Thisconstanteffortasconstantlytendstosubjectthelowerclassesofthesocietytodistressandtopreventanygreatpermanentameliorationoftheircondition。
  Thewayinwhich,theseeffectsareproducedseemstobethis。Wewillsupposethemeansofsubsistenceinanycountryjustequaltotheeasysupportofitsinhabitants。Theconstantefforttowardspopulation,whichisfoundtoacteveninthemostvicioussocieties,increasesthenumberofpeoplebeforethemeansofsubsistenceareincreased。Thefoodthereforewhichbeforesupportedsevenmillionsmustnowbedividedamongsevenmillionsandahalforeightmillions。Thepoorconsequentlymustlivemuchworse,andmanyofthembereducedtoseveredistress。
  Thenumberoflabourersalsobeingabovetheproportionoftheworkinthemarket,thepriceoflabourmusttendtowardadecrease,whilethepriceofprovisionswouldatthesametimetendtorise。Thelabourerthereforemustworkhardertoearnthesameashedidbefore。Duringthisseasonofdistress,thediscouragementstomarriage,andthedifficultyofrearingafamilyaresogreatthatpopulationisatastand。Inthemeantimethecheapnessoflabour,theplentyoflabourers,andthenecessityofanincreasedindustryamongstthem,encouragecultivatorstoemploymorelabourupontheirland,toturnupfreshsoil,andtomanureandimprovemorecompletelywhatisalreadyintillage,tillultimatelythemeansofsubsistencebecomeinthesameproportiontothepopulationasattheperiodfromwhichwesetout。Thesituationofthelabourerbeingthenagaintolerablycomfortable,therestraintstopopulationareinsomedegreeloosened,andthesameretrogradeandprogressivemovementswithrespecttohappinessarerepeated。
  Thissortofoscillationwillnotberemarkedbysuperficialobservers,anditmaybedifficultevenforthemostpenetratingmindtocalculateitsperiods。Yetthatinalloldstatessomesuchvibrationdoesexist,thoughfromvarioustransversecauses,inamuchlessmarked,andinamuchmoreirregularmannerthanI
  havedescribedit,noreflectingmanwhoconsidersthesubjectdeeplycanwelldoubt。
  Manyreasonsoccurwhythisoscillationhasbeenlessobvious,andlessdecidedlyconfirmedbyexperience,thanmightnaturallybeexpected。
  Oneprincipalreasonisthatthehistoriesofmankindthatwepossessarehistoriesonlyofthehigherclasses。Wehavebutfewaccountsthatcanbedependeduponofthemannersandcustomsofthatpartofmankindwheretheseretrogradeandprogressivemovementschieflytakeplace。Asatisfactoryhistoryofthiskind,ononepeople,andofoneperiod,wouldrequiretheconstantandminuteattentionofanobservingmindduringalonglife。Someoftheobjectsofinquirywouldbe,inwhatproportiontothenumberofadultswasthenumberofmarriages,towhatextentviciouscustomsprevailedinconsequenceoftherestraintsuponmatrimony,whatwasthecomparativemortalityamongthechildrenofthemostdistressedpartofthecommunityandthosewholivedrathermoreattheirease,whatwerethevariationsintherealpriceoflabour,andwhatweretheobservabledifferencesinthestateofthelowerclassesofsocietywithrespecttoeaseandhappiness,atdifferenttimesduringacertainperiod。
  Suchahistorywouldtendgreatlytoelucidatethemannerinwhichtheconstantcheckuponpopulationactsandwouldprobablyprovetheexistenceoftheretrogradeandprogressivemovementsthathavebeenmentioned,thoughthetimesoftheirvibrationsmustnecessarilyberenderedirregularfromtheoperationofmanyinterruptingcauses,suchastheintroductionorfailureofcertainmanufactures,agreaterorlessprevalentspiritofagriculturalenterprise,yearsofplenty,oryearsofscarcity,warsandpestilence,poorlaws,theinventionofprocessesforshorteninglabourwithouttheproportionalextensionofthemarketforthecommodity,and,particularly,thedifferencebetweenthenominalandrealpriceoflabour,acircumstancewhichhasperhapsmorethananyothercontributedtoconcealthisoscillationfromcommonview。
  Itveryrarelyhappensthatthenominalpriceoflabouruniversallyfalls,butwewellknowthatitfrequentlyremainsthesame,whilethenominalpriceofprovisionshasbeengraduallyincreasing。Thisis,ineffect,arealfallinthepriceoflabour,andduringthisperiodtheconditionofthelowerordersofthecommunitymustgraduallygrowworseandworse。Butthefarmersandcapitalistsaregrowingrichfromtherealcheapnessoflabour。Theirincreasedcapitalsenablethemtoemployagreaternumberofmen。Workthereforemaybeplentiful,andthepriceoflabourwouldconsequentlyrise。Butthewantoffreedominthemarketoflabour,whichoccursmoreorlessinallcommunities,eitherfromparishlaws,orthemoregeneralcauseofthefacilityofcombinationamongtherich,anditsdifficultyamongthepoor,operatestopreventthepriceoflabourfromrisingatthenaturalperiod,andkeepsitdownsometimelonger;

  Butthoughtherichbyunfaircombinationscontributefrequentlytoprolongaseasonofdistressamongthepoor,yetnopossibleformofsocietycouldpreventthealmostconstantactionofmiseryuponagreatpartofmankind,ifinastateofinequality,anduponall,ifallwereequal。
