TY  - JOUR
AB  - One   of   the   pressing   social   concerns   of   our   timeis  the  need  for  meaningful  responses  to  migrantsand   refugees   fleeing   conflict   and   environmentalcatastrophe.  We  develop  a  computational  model  tomodel  the  influx  of  migrants  into  a  city,  varyingthe   rates   of   entry,   and   find   a   non-linear   inverserelationship between the fraction of resident populationwhose  tolerance  levels  are  breached  due  to  migrantentry   and   the   average   time   to   such   tolerancebreach.  Essentially,  beyond  a  certain  rate  of  migrantentry,   there   is   a   rapid   rise   in   the   fraction   ofresidents whose tolerances are breached, even as theaverage  time  to  breach  decreases.  We  also  modelan  analytical  approximation  of  the  computationalmodel  and  find  qualitative  correspondence  in  theobserved  phenomenology,  with  caveats.  The  sharpincrease  in  the  fraction  of  residents  with  tolerancebreach  could  potentially  underpin  the  intensity  ofresident  responses  to  bursts  of  migrant  entry  intotheir  cities.  Given  this  non-linear  relationship,  it  isperhaps essential that responses to refugee situationsare   multi-country   or   global   efforts   so   that   sharpspikes of refugee migrations are equitably distributedamong nations, potentially enabling all participatingcountries   to   avoid   impacting   resident   tolerancesbeyond limits that are socially sustainable.
