Somebody’s numbers are off. If Nasi’s birth data is accurate (seemingly far more reliable than attempts to verify school data) there will be a crisis no matter how you manipulate the school data. Are their numbers off?
Nasi’s numbers are far off from state published birth data, which includes all Lakewood births.
https://www-doh.state.nj.us/doh-shad/query/result/birth/BirthBirthCnty/Count.htmlNasi:
2000 - 640 boys, 631 girls = 1,271
NJ data - 977 boys, 967 girls = 1,944
65% of total
2001 - 814 boys, 734 girls = 1,548
NJ data - 1,145 boys, 1,055 girls = 2,200
70% of total
2002 - 862 boys, 810 girls = 1,672
NJ data - 1,210 boys, 1,155 girls = 2,365
70% of total
Also interesting - to note how the ratio changes drastically and definitely has an impact
2000 boys - Nasi 640 vs state 977 (65.5%)
2003 girls - Nasi 922 vs state 1,269 (72.6%)
2001 boys - Nasi 814 vs state 1,145 (71%)
2004 girls - Nasi 975 vs state 1,348 (72.3)
Though overall based on the state data for Lakewood there should be an age gap (assuming every birth becomes a frum eligible bachelor/bachelorette), though not as drastic as what Nasi presents
