Amaxabiso okuzalwa aMaqela
Ngamanye amaxesha kubonakala ngathi kunamawele apho ubheka khona. Kodwa xa uhlalutya idatha yedini lokuzalwa e-United States, unokubona ukuba kukho ezinye iindawo ezijoliswe kuzo kwindawo ezithile. Isilinganiso sezabelo ezizalwe ngamawele ziphakama ngamaphesenti angama-76 ukususela ngo-1980 ukuya ku-2011 ukusuka ku-18.9 ukuya ku-1000 ukuya phezulu kwi-33.9 ngonyaka ka-2014 ngo-2014, kodwa uye wazinzisa okanye wahamba ngokunyuka ngaphantsi komnyaka. I-Triplet kunye ne-high-order order births ezininzi ziye zahla ngenxa yokuphakama kwazo ngo-1998 kwaye ziyaqhubeka nokuhla ngonyaka.
Amazwe aneNqanaba eliPhezulu kakhulu lokuBulawa kweTwin
Amazwe anesantya esiphezulu sokuzalwa kwababini ahlala eNew Jersey, eMassachusetts nase-Connecticut. Ngo-2016, inani lamazwe ngamawele lalingama-33.4 kwi-1,000 abazalwa ngokuzalwa. Kodwa ezi zintathu zikhankanywe ngaphezu koko, kwaye zibeke isikhundla sabo esiphambili iminyaka embalwa.
Amazwe aneNqanaba eliPhezulu kakhulu lokuBulawa kweTwin
- I-Connecticut 41.3 / 1,000 yokuzalwa ngokuzalwa (4,463 amawele okuzalwa)
- ISithili saseColumbia 40.4 / 1,000 abazalwa ngokuzalwa (1,170 ii-twin births)
- I-Jersey Jersey 40.1 / 1,000 yokuzalwa ngokuzalwa (12,381 amawele okuzalwa)
- EMassachusetts 38.3 / 1,000 abazalwa ngokuzalwa (8,228 amawele okuzalwa
Ukuzalwa kwama-Twin kuya kulinganiswa ngokumalunga nenani elipheleleyo lokuzalwa ngokutsha kwimeko. Kutheni kutheni kunamaqondo amaninzi amakhulu eamawele kule mpuma kumntla-mpuma? Iingcamango ezininzi zinikwe ukucacisa ukuba kutheni amaxabiso aphezulu kakhulu kula mazwe.
Inqaku e-Boston Globe libonisa ukuba iMassachusetts inika inhlanganisela "inani elikhulu ngokungaqhelekanga lokukhulelwa kwabasetyhini abadala" kunye "nokuxhomekeka okukhulu kwiindlela zokwelapha ezingafumanekiyo." NjengoNew Jersey neConnecticut, iMassachusetts inabantu abaninzi amaqela, apho abacebileyo, abafazi abaqeqeshwayo kakhulu baphishekela imisebenzi xa bebancinci kwaye belibazise ukuzala abantwana bade bekhulile. Akunabo kuphela oomama abadala abakwazi ukukhulelwa amawele, kodwa ngokungafaniyo, banakho amathuba okuba neengxaki zokukhulelwa, kwaye ngokulandela ukufumana uncedo lokuzalana. Ukunyanga okuvelisayo kunokuba kubiza, kodwa eMassachusetts, iindleko zifakwe i-inshurensi.
Amazwe aneNinzi yeTwin Births
Nangona la mazwe anamazinga aphezulu azalwa ngamawele, awayekho apho apho inani lamamawele azalwa khona ngonyaka onikeziweyo. Kungenxa yokuba amazwe anabantu abaninzi kakhulu, njengaseTexas, eCalifornia naseNew York, nabo babone ukuzalwa okuphindwe kabini. Ngokomzekelo, amawele angama-46,559 azalelwa eCalfornia ngo-2014. Kodwa izinga labazali ababelekileyo lilingama-31 kuphela kwaba-1 000 abazalwa ngokuzalwa, ngaphantsi kwezinga likazwelonke.
Amazwe aneNinzi yeTwin Births
- I-California 46,150 (i-31.1 / 1,000 yokuzalwa ngokuzalwa)
- I-Texas 37,664 (i-31.3 / 1,000 yokuzalwa ngokuzalwa)
- ENew York 25,879 (ii-36.4 / 1,000 zokuzalwa eziphilayo)
Amazwe Ngeentlobo eziMnandi
Mhlawumbi nawe unomdla ukwazi apho awele khona amawele.
Amazwe aneNqanaba elingaphantsi kweTwin Birth Birth
- INew Mexico 23.9 / 1,000 abazalwa ngokuzalwa (1,832 ii-twin births)
- E-Arizona 29.6 / 1,000 abazalwa ngokuzalwa (7,606 amawele okuzalwa)
- I-Arkansas i-29.6 / 1,000 yokuzalwa ngokuzalwa (3,426 amawele okuzalwa)
Amazwe anomhlaba ongathandekiyo weewele
- I-Vermont 635 (35.7 / 1,000 yokuzalwa ngokuzalwa)
- I-Wyoming 731 (32.01,000 abazalwa ngokuzalwa)
- I-Delaware 993 (i-30.0 / 1,000 yokuzalwa ngokuzalwa)
