Introduction
On2010,PuertoRicowokeuptoanunspokenreality;thepopulationoftheislandwas
decreasing(Figueroa‐Rodriguezandcolleagues,2012).The2010Censusindicatedthatthe
populationoftheislandsummed3,725,789persons(USCensus,2010).Forthe2000periodthe
populationoftheislandaddedupto3,808,610persons.Acomparisonofbothcensuscounts
evidencesthefirstpopulationdeclineofPuertoRico,adeclineof2.17%.Thelongheld
expectationthattheislandwouldreach4millioninhabitantsdissolvedwhilethegovernment
receivedwithsurprisethealarmingnews.
Despitehavinganunstabletrajectorywithregardstopopulationgrowth,apopulation
declinehadnotbeenprojectedbyacademics,researchers,planningcentersorbygovernment
authorities.ThepurposeofthispaperistoprojectthepopulationofPuertoRicowhile

Finally,thehistoryofPuertoRicohasbeenmarkedbyconstantmigration.Duringthe

theAmericanCommunitySurvey(ACS)themedianageforemigrantsoscillatesbetween27to

LIMITATIONS
Weidentifiedthreekeylimitationsforourstudy.ThefirstisthatPuertoRicostopped
collectingrace/ethnicbackgroundsafterthe1990Census.Thedecisionbasedinthenotionthat
“weareallPuertoRicans”hasleftagapinhowwecanaddressandunderstand
transformationsbasedintheethnicbackgroundofthepopulationoftheisland.Astepforward
couldbetostartcollectingthisinformationnotonlyinspecialformsintheDecennialCensus
butalsoinbirthanddeathcertificates,aswellasinfuturepopulationbasedsurveys.Policy
makersshouldrescuetheethnicbackgroundcategoriesthatreflectedthehistoricaland
demographicrootsofsomesectorofthepopulation.
Thesecondlimitationwefoundwaswiththecalculationofnetmigrationrates,
althoughweperformedvarioussensitivityanalyseswereliedonactualtrendsandnon‐
publishedinformationtoallowsomevariationinthemigrationratesforthepost‐2010years.
Thisallowedustobeconservativewithregardstothemagnitudeofnetmigrationandits
impactinourpopulationprojections.
Athirdlimitationemergesfromtheabsenceofdemographicliteraturethatdealswith
thePuertoRicopopulationdynamicsapartfromworkfromthelate90s,andearly2000smost
