Idadi ya sasa ya watu duniani ni takriban watu bilioni 8.30, kulingana na ufuatiliaji wa hivi karibuni wa idadi ya watu na makadirio ya kimataifa katika nchi 215. Hatua hii muhimu inaonyesha upanuzi mkubwa wa spishi ya binadamu katika karne mbili zilizopita, ukichochewa na maendeleo katika tiba, kilimo, na afya ya jamii.
Idadi ya Watu Duniani (Kihistoria)
Kwa sehemu kubwa ya historia ya binadamu, idadi ya watu duniani ilikua kwa kasi ndogo sana, ikidhibitiwa na viwango vya juu vya vifo na upatikanaji mdogo wa chakula. Karibu mwaka 8000 KK, mwanzoni mwa mapinduzi ya kilimo, jumla ya idadi ya watu ilikadiriwa kuwa watu milioni 5 tu. Ukuaji uliendelea kuwa wa taratibu kwa milenia nyingi, ukifikia takriban watu milioni 300 mwanzoni mwa enzi ya kawaida. Kupungua pekee kwa kiasi kikubwa katika historia iliyorekodiwa kulitokea wakati wa karne ya 14, wakati Kifo Cheusi kilipopunguza idadi ya watu duniani kutoka takriban milioni 450 hadi milioni 370. Kupona kutokana na janga hili kuliashiria mwanzo wa mwelekeo endelevu wa kupanda ambao hatimaye ungesababisha mlipuko wa kisasa wa idadi ya watu. Wakati wa karne ya 18, Mapinduzi ya Viwanda yalibadilisha kimsingi idadi ya watu kwa kuboresha usafi, lishe, na huduma za afya. Maendeleo haya yalisababisha kupungua kwa kiasi kikubwa kwa viwango vya vifo, na kusababisha idadi ya watu kufikia bilioni 1 kwa mara ya kwanza mnamo 1804. Karne za 19 na 20 ziliona ukuaji ukiongezeka zaidi huku umri wa kuishi ukiongezeka na vifo vya watoto vikipungua sana. Kati ya 1930 na 1960 pekee, ulimwengu uliongeza watu wengine bilioni 1, jambo ambalo hapo awali lilikuwa limechukua historia yote ya binadamu kufikiwa. Karne ya 20 ilifafanuliwa na ukuaji huu wa mlipuko, ambao uliona idadi ya watu ikiongezeka karibu mara nne. Kipindi hiki cha upanuzi wa haraka kilifikia kilele mwishoni mwa miaka ya 1960, wakati ambapo viwango vya uzazi vilisalia juu huku viwango vya vifo vikishuka kwa kasi. Tangu wakati huo, ingawa jumla ya idadi ya watu imeendelea kuongezeka, kasi ya ukuaji imeingia katika kipindi cha kupungua kwa kasi kutokana na mabadiliko ya kijamii na kuenea kwa upangaji uzazi.

Kiwango cha Ongezeko la Watu kwa Mwaka (%)
Kiwango cha Ukuaji wa Idadi ya Watu
Kiwango cha ukuaji wa kila mwaka wa idadi ya watu duniani kilifikia kilele chake cha kihistoria katikati ya miaka ya 1960, kilipokuwa takriban 2.1%. Tangu kipindi hicho, kiwango hicho kimeingia katika upungufu wa muda mrefu, hivi karibuni kikishuka hadi takriban 0.9% kwa mwaka. Upungufu huu unachochewa kimsingi na mabadiliko ya idadi ya watu, huku mataifa yakihama kutoka viwango vya juu vya kuzaliwa na vifo kwenda kwenye hali ya uzazi wa chini na maisha marefu. Sababu kama vile kuongezeka kwa ufikiaji wa elimu kwa wanawake, uhamiaji wa mijini, na kuboreshwa kwa utulivu wa kiuchumi kumechangia ukubwa mdogo wa familia katika mabara mengi. Takwimu za hivi karibuni zinaonyesha kuwa idadi ya watu wanaoongezwa duniani kila mwaka pia imeanza kutulia. Wakati idadi ya watu kwa sasa inaongezeka kwa takriban watu milioni 73 kila mwaka, ongezeko hili la jumla linakadiriwa kupungua kadiri nchi nyingi zinavyofikia au kushuka chini ya kiwango cha uzazi cha 2.1 cha watoto kwa kila mwanamke. Kwa sasa, zaidi ya 50% ya idadi ya watu duniani wanaishi katika maeneo ambayo uzazi uko chini ya kiwango hiki cha uingizwaji, mwelekeo unaoashiria utulivu wa baadaye wa idadi ya watu.

Kulingana na Mapitio ya Matarajio ya Idadi ya Watu Duniani ya 2024, idadi ya watu duniani inakadiriwa kuendelea na mwelekeo wake wa kupanda kwa miongo kadhaa kabla ya kufikia utulivu. Mifumo ya sasa inaonyesha idadi ya watu Duniani itafikia kilele cha takriban bilioni 10.3 wakati wa katikati ya miaka ya 2080. Kufuatia kilele hiki, idadi ya watu inatarajiwa kupungua polepole, ikifikia takriban bilioni 10.2 ifikapo mwaka 2100. Mabadiliko haya yanaashiria hatua muhimu katika historia ya binadamu, kwani enzi ya upanuzi wa haraka inatoa nafasi kwa kipindi cha utulivu wa idadi ya watu. Asili ya ukuaji wa baadaye itakuwa isiyo sawa, huku karibu ongezeko lote lililokadiriwa likitokea katika maeneo yanayoendelea. Wakati nchi nyingi zenye mapato ya juu na ya kati tayari zinakabiliwa na kuzeeka na kupungua kwa idadi ya watu, Afrika Kusini mwa Sahara na sehemu za Kusini mwa Asia zitaendelea kuongeza jumla ya idadi ya watu duniani. Ifikapo 2050, inakadiriwa kuwa zaidi ya nusu ya ukuaji wa idadi ya watu duniani utajikita katika nchi nane tu, ikionyesha mabadiliko makubwa ya kitovu cha idadi ya watu duniani kuelekea bara la Afrika.

Hatua muhimu za idadi ya watu zinaonyesha kasi ya ukuaji inayoongezeka tangu karne ya 19. Ilichukua historia yote ya binadamu kufikia watu bilioni 1 mnamo 1804, lakini miaka 126 tu kufikia bilioni 2 mnamo 1930. Hatua zilizofuata zilivukwa kwa kasi ya ajabu: bilioni 3 mnamo 1960, bilioni 4 mnamo 1974, bilioni 5 mnamo 1987, bilioni 6 mnamo 1999, bilioni 7 mnamo 2011, na bilioni 8 mnamo 2022. Makadirio ya baadaye yanaonyesha kuwa ulimwengu unaweza kufikia bilioni 9 mnamo 2037 na bilioni 10 karibu mwaka 2061, huku vipindi kati ya kila hatua ya watu bilioni moja vikianza kutanuka tena.

Viwango vya ukuaji wa kikanda vinapimwa kwa idadi ya watu kutoka kwa viashiria vya hivi karibuni vya ukuaji wa nchi pale vinapopatikana. Vinaonyeshwa kama muktadha wa mwelekeo, si saa rasmi zinazojitegemea za bara.
Asia inasalia kuwa bara lenye watu wengi zaidi, kwa sasa likiwa na takriban 59% ya watu duniani. Eneo hili linajumuisha mataifa mawili makubwa zaidi, India na China, ambazo kwa pamoja zinachangia zaidi ya 35% ya jumla ya idadi ya watu. Afrika ndilo eneo linalokua kwa kasi zaidi na sasa linawakilisha takriban 18% ya jumla ya kimataifa, sehemu ambayo inatarajiwa kuongezeka kwa kiasi kikubwa katika miongo ijayo huku maeneo mengine yakipata ukuaji wa polepole au kupungua. Ulaya kwa sasa inachangia takriban 9% ya idadi ya watu duniani, lakini ndilo bara pekee linalokabiliwa na upungufu wa asili wa kudumu huku vifo vikianza kuzidi kuzaliwa. Amerika kwa pamoja ina takriban 13% ya watu duniani, huku Amerika ya Kusini na Karibiani zikiwakilisha 8% na Amerika ya Kaskazini ikichangia 5%. Oceania inasalia kuwa eneo lenye watu wachache zaidi linalokaliwa, ikichangia chini ya 1% ya jumla ya idadi ya watu ikiwa na takriban wakazi milioni 46.
Idadi ya Watu Duniani kwa Dini
Idadi ya watu kidini inaonyesha kuwa Ukristo ndio kundi kubwa zaidi, likiwakilisha takriban 31% ya idadi ya watu duniani. Uislamu ni wa pili kwa ukubwa na dini kuu inayokua kwa kasi zaidi, kwa sasa ikichangia takriban 25% ya watu duniani. Wale ambao hawajihusishi na dini yoyote, wakiwemo watu wasioamini Mungu na wasio na uhakika, wanaunda kundi la tatu kwa ukubwa kwa takriban 16%, ingawa baadhi ya tafiti za hivi karibuni zinaonyesha sehemu hii inaweza kuwa juu hadi 24% katika maeneo maalum. Uhindu ni kundi la nne kwa ukubwa la kidini, likifuatwa na takriban 15% ya idadi ya watu duniani, huku idadi kubwa ya wafuasi wake wakiishi Kusini mwa Asia. Ubuddha unachangia takriban 7% ya jumla, wakati dini za kienyeji na mifumo mingine midogo ya imani inaunda 6% iliyobaki. Usambazaji wa kijiografia wa makundi haya umejikita sana, huku karibu 99% ya Wahindu na Wabudha wakiishi katika eneo la Asia-Pasifiki.
Msongamano wa Watu Duniani
Wastani wa msongamano wa watu katika eneo la ardhi la Dunia ni takriban watu 60/km² (watu 155/maili ya mraba). Takwimu hii ni wastani katika ardhi yote inayokaliwa, ingawa msongamano halisi unatofautiana sana kutokana na hali ya hewa, topografia, na ukuaji wa miji. Bangladesh ndiyo nchi kubwa yenye msongamano mkubwa zaidi wa watu, ikiwa na zaidi ya watu 1,100/km² (watu 2,849/maili ya mraba), wakati miji-dola kama Singapore na Monaco inafikia viwango vya juu zaidi. Kinyume chake, maeneo makubwa yanasalia na watu wachache kutokana na mazingira magumu. Nchi kama Mongolia, Namibia, na Iceland zina msongamano wa chini ya watu 4/km² (watu 10/maili ya mraba). Takriban 50% ya idadi ya watu duniani wanaishi kwenye 1% tu ya eneo lake la ardhi, hasa katika maeneo ya pwani na mabonde makubwa ya mito ambapo rasilimali ni nyingi zaidi.
Jinsi ya Kusoma Makadirio Haya ya Idadi ya Watu
Ni mfano, si sensa
Saa ya moja kwa moja huanza kutoka kwa misingi rasmi ya idadi ya watu na kutumia viwango vinavyokadiriwa kwa muda uliopita. Hakuna chanzo kinachohesabu kila tukio la kuzaliwa, kifo, au uhamiaji ulimwenguni kwa wakati halisi.
Viwango vinatokana na data ya kila mwaka
Kuzaliwa, vifo, ukuaji, na makadirio ya kila siku ya jedwali la nchi hubadilisha viashiria vya idadi ya watu vya kila mwaka kuwa maadili ya kila sekunde au kila siku kwa kulinganisha na kuelimisha.
Marekebisho ni ya kawaida
Takwimu za UN, World Bank, na za kitaifa hurekebishwa kadiri sensa na tafiti zinavyoboreka. Chukulia tarakimu kamili kama taswira ya ukubwa na mwelekeo, si hesabu ya kisheria au rasmi.
Vyanzo na Mbinu
Takwimu na makadirio yaliyowasilishwa kwenye ukurasa huu yametolewa kutoka kwa Mapitio ya Matarajio ya Idadi ya Watu Duniani ya 2024 ya Idara ya Idadi ya Watu ya Umoja wa Mataifa na Hifadhidata ya Kimataifa ya Ofisi ya Sensa ya Marekani. Mashirika haya yanatumia mchanganyiko wa data ya sensa ya kitaifa, rekodi za usajili wa matukio muhimu, na tafiti za kaya ili kufuatilia mienendo ya idadi ya watu. Data ya ziada ya idadi ya watu kidini inatolewa na Pew Research Center, ambayo huchanganua maelfu ya vyanzo ili kukadiria muundo wa kidini duniani. Takwimu zote zinategemea sasisho za mara kwa mara kadiri matokeo mapya ya sensa na tafiti za idadi ya watu zinavyopatikana.
Maswali Yanayoulizwa Mara kwa Mara
Idadi ya sasa ya watu duniani ni takriban watu bilioni 8.30. Takwimu hii inakokotolewa kulingana na data ya hivi karibuni ya idadi ya watu katika nchi na maeneo 215. Wakati jumla ya idadi ya watu inaendelea kukua, kiwango cha ongezeko cha kila mwaka kimepungua sana tangu kilele chake mwishoni mwa miaka ya 1960.
Takriban watoto 360,000 wanazaliwa kila siku ulimwenguni kote. Baada ya kuhesabu vifo vya kila siku, idadi ya watu duniani hupata ongezeko la jumla la takriban watu 200,000 kila baada ya saa 24. Hii inasababisha nyongeza ya kila mwaka ya zaidi ya watu milioni 70 kwa jumla ya idadi ya watu.
Idadi ya watu duniani inakadiriwa kufikia watu bilioni 10 karibu mwaka 2061. Hatua hii muhimu inawakilisha kipindi cha ukuaji wa polepole, kwani viwango vya uzazi vinaendelea kupungua ulimwenguni kote. Sehemu kubwa ya ukuaji unaoelekea kwenye hatua hii inatarajiwa kutokea katika mataifa yanayoendelea kote Afrika Kusini mwa Sahara na Asia.
India kwa sasa ndiyo nchi yenye watu wengi zaidi duniani, ikiwa na idadi ya watu inayokadiriwa kuwa zaidi ya bilioni 1.44. Hivi karibuni iliipita China, ambayo sasa inashika nafasi ya pili kwa kuwa na wakazi takriban bilioni 1.42. Marekani inashika nafasi ya tatu ikiwa na idadi ya watu takriban milioni 345.
Idadi ya watu duniani kwa sasa inakua, lakini kasi ya ukuaji iko katika kiwango chake cha chini kabisa tangu miaka ya 1950. Data ya hivi karibuni inaonyesha kiwango cha ukuaji wa kila mwaka cha takriban 0.9%. Wakati jumla ya idadi ya watu inaendelea kuongezeka, nchi nyingi binafsi sasa zinakabiliwa na kudumaa au kupungua kwa asili kwa idadi ya watu.
Idadi ya watu duniani inakadiriwa kufikia takriban watu bilioni 9.7 ifikapo mwaka 2050. Makadirio haya kutoka Umoja wa Mataifa yanaonyesha kuwa ukuaji utajikita katika idadi ndogo ya nchi. Maeneo yanayoendelea barani Afrika na Asia yanatarajiwa kuchochea sehemu kubwa ya ongezeko hili katika miongo ijayo.
Takriban watu bilioni 117 wameishi Duniani katika historia yote ya binadamu. Makadirio haya, yaliyotolewa na Population Reference Bureau, yanachukulia kuwa binadamu wa kisasa walitokea takriban miaka 50,000 iliyopita. Kulingana na takwimu hizi, idadi ya sasa ya watu duniani inawakilisha takriban 7% ya wanadamu wote waliowahi kuwepo.
Idadi ya watu duniani inapimwa kwa kujumlisha data ya sensa ya kitaifa, tafiti za kaya, na rekodi za usajili wa matukio muhimu kutoka nchi binafsi. Mashirika ya kimataifa kama Umoja wa Mataifa na Ofisi ya Sensa ya Marekani kisha hutumia mifumo ya takwimu kwenye data hizi. Mchakato huu huzingatia mapungufu ya data na kutoa makadirio sahihi ya wakati halisi ya idadi ya watu.
