Soo koob maqaalka:  Tirada da 'yarta darawallada baabuurta rakaabka ah ee ku lugta leh shilalka baabuurta ee Maraykanka ayaa hoos uga dhacay 5,724 ilaa 2,568, 100,000 qofkiiba tobankii sano ee la soo dhaafay. Sida laga soo xigtay warbixin Maraykan ah, tirada shilalka baabuurta ee ay ku dhintaan da'yarta darawalada ah ayaa hoos u dhacday boqolkiiba 55 tobankii sano ee la soo dhaafay. Inta u dhaxaysa 2004 iyo 2013, tirada darawalada gawaarida rakaabka ee da'doodu u dhaxayso 16 ilaa 19 oo ku lug leh shilalka dhimashada ee Mareykanka ayaa hoos uga dhacay 5,724 ilaa 2,568, 100,000 qofba. Tilmaamaha cusub ee badbaadada baabuurta iyo xaddidaadda laysanka ayaa ka mid ah sababaha ugu waaweyn ee hoos u dhaca weyn ee shilalka. Ruth Shults, oo ah cilmi baare ka tirsan ka hortagga dhaawacyada Xarunta Xakamaynta iyo Ka Hortagga Cudurrada ee Atlanta ee Maraykanka oo ka shaqeysay warbixinta, ayaa sheegtay in laysanka la qaatay uu hoos u dhigo guud ahaan heerka shilalka ee darawalada da'da yar 20 ilaa 40 boqolkiiba. Ruqsadaha baabuurta ee la kala wareejiyay waxay sababi karaan in la xiro baabuurta dhalinyarada ah, iyadoo la yareynayo tirada dhalinyarada wadooyinka maraysa habeenkii. Noocyada noocan ah ee ruqsadaha ayaa sidoo kale xaddidi kara tirada rakaabka ee darawalka cusub uu ku qaadan karo baabuurkiisa, sida laga soo xigtay Autoblog. Dowladaha qaarkood waxay ku xaddidaan darawalada da'da yar hal rakaab, halka kuwa kale ay u oggolaadaan oo keliya qaraabada iyo barayaasha wadista. Waqtiga ku saabsan, gobolada qaar, sida Idaho, uma oggola darawallada da'da yar inay wadada maraan laga bilaabo qorrax dhaca ilaa qorrax soo baxa. Wadamada kale waxay leeyihiin waqtiyo gaar ah, sida 11-ka fiidnimo ilaa 5-ta subaxnimo ama 12-ka subaxnimo ilaa 6-ta subaxnimo. Da'da ay ku kala duwan yihiin liisanka darawalnimada ee laga bilaabo bilowga illaa dhexdhexaadka illaa darawalnimada buuxda ayaa sidoo kale ku kala duwan gobollada. Eric Teoh, oo ah sarkaal sare oo tirakoob ka sameeya wadooyinka oo ka tirsan hay'adda caymiska ee nabadgelyada wadooyinka ee Arlington, Virginia, oo aan ku lug lahayn daraasadda ayaa sheegay in dhalinyarada da'da yar aysan u muuqan inay ku sii jeedaan darawalka, taas oo macnaheedu yahay in shilalka yaryar ay dhici karaan. Celcelis ahaan, saddex ka mid ah afartii arday ee dugsiyada sare ee Maraykanka oo da'doodu tahay 16 sano ama ka weyn ayaa sheegay inay wadeen baabuur 30kii maalmood ee la soo dhaafay markii ay wareysi siinayeen. '18-sano-jir cusub ayaa laga yaabaa inuu ka diyaarsan yahay qaan-gaarnimada 16-sano jir cusub,' ayuu u sheegay Autoblog. Saddex ka mid ah afarta arday ee wax ka barta dugsiyada sare ee Maraykanka da'doodu tahay 16 sano ama ka weyn waxay wadeen baabuur ugu yaraan hal mar 30kii maalmood ee ugu horeysay...
