CENSUS TUCICS IN [JiEHI C.&T C I TIES

Origin and history: of the census t r a c t . - Mom than 30 years ago D r . Walter Laidlaw, workiilg with p01w.lation s t a t i s t i c s ill Bow York, becsttnc convinced that i n order to study neigl~borlioods i t was absolutely uecasaary t o have population data fo r loca l urcas smallor tli,.ln 73orou,@is o r wards, and to es tabl ish those aroas so tlzat thoy would remain un- chaigod from census to censua, To him, therefore , gocs tho crodi t f o r i n i t i a t i n g tho Iclen, of the census t r a c t , o r , a s he ca l l sd i t , the 'I ~ a i l i t n ~ y d i c t r i c t .I1

I n current prac Lice the census t r ac t s are small areas , having a ~opul .a t ion usually betwean 3,000 and 8,000, iiito which a c i t y I s sub- divided, more o r Less ar 'b i t rar i ly , for s t n t i s t i c a l m d loca l adxiinis- t r a t i v e purposes, Tlie t r a c t s are perrnanes,bly es tabl ished, s o that corn- parisolzs m q be imds from year to yQ&T and from census $0 oensus; they are l a i d out with a view t a approximata wliformity i n pop~loticrn and with some regard l o r uniformity i n s izs ; ~tnd escli i s designad 'be in- clude an area f a i r l y homogeneoua i n population c h a r a c t s r i s f i c ~ r Tn .c? Lies where the ward l i n e s a r s infrequantly chmged, the t r a c t s form aubdxvi6'i0p8 of the wards; i n other c i t i e s they are l a i d out without regard t o the wzrd boruldaries.

P r i o r to the census o f 1910, Dr, L & l & l & w divides t b s c i t y o f New York i n to 40-aors t r ac t s , arranged for the tabule t ion of oeusus da ta fo r these areas, and persuaded the Bureau o f tlae Cenaus t o extexzd tthe plan of t r a c t tabulations t o the 7 other c i t i e s ht.~,ving ab tha t timo a pog?xlation o f 500,000 or more, Thea~ c i t i e s were Chicago, Philadel- phia, Clevolmd, S t , Louis, 3alti.morc, 90sl;On, and P i t t sbuxgh. While tlze tabulation was made by t r ac t s fo r these 7 c i t i e s , no imnlodia,'co us@ was made of the figurea except for NOW York City and POT S t . Lonis.

Tlie 1920 cellsus data were l ikewir ;~ Ln'bulated by t r a c t s f o r the same 1ia.t of cibies. The f i g ~ ~ r o s fo r New Yorlc wore tdcen off shorkly a f t e r the completion of tho tabula"cjon, and were publishod by Dr. Laid- law. 111 1925, Dr. Er l~est W. 3iiurgess bocx~ia i n t a r e s t ed i n the Chicago t r ac t t ~ b u l a t i o n s and made arraigemoilts f o r 2;dciiig o f f the f igures f o r both 1920 and 1910, These f igures were published i n 1931, 132 1926, M r . Howard Whipple Green made arrailgetilcnts bo obtain tho t r a c t tabula- t ions f o r CleveTancl, obtaining the data lilcowise f o r both 1920 and 1910, and supplemeating '%lie t r a c t f imrcs POX t bc c i t y of Cleveland with ce r ta in data f o r adjacent areas. Thene figures were published i n 1927. Between 1927 and 1930 several other c i t i e s bocnrne in tc res tod i n the census t r ac t iden to the extent of laying ant ten ta t ive t r a c t s and 0%-

The census t r ac t s woro l a id out i n thceo c i t i e s by a colnmittee representing local a rga l i ea tions end worlring i n cooporatioli with %he Bureau of the Ceasus. This conlrnittoe nlsa und.srtoolc t o provide funds f o r paying tho cos'l; of the extra work ilivol~ocl i n making the t abu la t ion of tho data by t r ac t s ra ther than for the c i t y as a whole, The new c i t i e s adcietl to the Xist wsrs Los Rngoles , B~r f f a l a , Washingtoa, Cincin- n a t i , Indinnapolis , CoI.~unbus, Bnshville , 3erlrc3ley, Syrncuso, and Yonlc- e r s , the l a s t t w o beinc added a t the so l i c i t a t i on ~f D r .

Sol.ectod items from Ghc 1939 population census were therefore tcib- u la ted by t r ac t s f o r 18 c i t i c s , In a few of tho c i t i e s the l oca l or- ganizations l a s t i n t a r e s t i n tho data or found themsolvos wlablo t o ra i so the f ~ u ~ d o necessary t o pay tlio cost of making u~ the f i n a l t ab los ; but org,miaations o r individuals in nloat of t l i o c i t i e s obtained from the Bureau of tho Census a l l o r a cansiclerable p a r t of Glzo s t a t i s t i c s covered by the apocznl t r a c t tabulations. 111 mazy 09 tliosc c i t i e s ax4 rangements were rnsde t o publish the t r a c t s2;a t is t ics ; mid i n the others copies have been mada nvailabla 'Go local organizations haviiig need. f o r them.
