Population s i z e , d i s t r i b u t i o n , urbanization and migration patterns a r e described, and estimates are made of levels, trends and regional d i f f e r e n t i a l s in mortality, f e r t i l i t y , natural increase and population growth. The construction and results of population projections f o r the next 30 years a t national, urban and r u r a l level a r e a l s o described. Ln summary, f e r t i l i t y l e v e l s a r e generally high, though still depressed i n some areas by widespread pathological sterility. Nortality l e v e l s a r e generally moderately low by African standards and declining, though there is c l e a r d i f f e r e n t i a l between the urbanized line-of-rail provinces and the r u r a l , l e s s developed off-line-rail provinces. National population growth is therefore high and r i s i n g , though provincial growth r a t e s vary s u b s t a n t i a l l y due to the massive r u r a l t o urban n i g r a t i o n i n recent decades t h a t has mcie Zambia one of the most heavily urbanized countries i n Arica. lrepared by: Althea X i 1 1 Population, Bealth and Nutrition Department July 1983 Table of Contents Page No. Sources of Data ................................................

The Demography of Zambia Sources of Data Zambia has had three f u l l censuses i n 1961/63, 1969 and 1980, a sample census i n 1376, and a national deaographic sample survey i n 1950/51. There have a l s o been a few small-scale demographic studies, most notably i n 1968/69 and 1979. Vital r e g i s t r a t i o n is to all i n t e n t s and purposes n e g l i g i 5 l e . The 1950/51 Deaographic Sample Survey %fore 1950, the only d a o g r a p h i c i n f o m a t i o n available f o r t h e African population was the s e r i e s of annual estimates of t o t a l population by . the Provin.cia1 Administration, probably based largely on tax records. The 1950 Demographic Sample Survey was an attempt t o provide some i l s e l i n e data; i t was carried out over a period of a year (Yay 1950 - liay 1951) but most of the f i e l d work was done during the summer of 1950 and the veighted average d a t e of survey was the f i r s t fortnight of July 1950. Besides including the f i r s t actu.al enumeration of the *tican population, the survey collected infomation on age ( i n three age classes, under one year, one year t o puberty and over puberty) , h i r t h s and deaths (distinguishing inlanc deaths) during the ?revious 12 clonths, and f o r each adult woman personally interviewed the cumbers of children ever born and children s t i l l surviving. The interviewers were European o f f i c e r s of the Provincial &&idstration, a s s i s t e d by African glddes and interpreters; f i d d work had t o be f i t t e d into t h e i r noraal duties and :raining consisted only of d i s t r i b u t i o n of derailed v r i t t e n instructions. Given the Lack of age d e t a i l , and the summary aature of the survey report, i t is h p o s s i b l e to evaluate f u l l y the quality of the 1950 data. The a c t u a l ecuseration appears :o have been very d e f i c i e n t , and it is l i k e l y t h a t the age f e r t i l i t y and a o r t a l i t y data a r e not g e z e r d l y reliable. This vould hardly be s u r ? r i s i q i n a pioneer survey carried out by untrained and inexperienced foreign intemievers . However much of the information collectetl is interesting and suggestive, and is occasionallg valuable. The 1961 and 1963 Censuses The 'irst r e a l census of Zambia was held in September 1961, when the de facto non-.African p p u l a t i o n was enmerated together with a census of nrban ea?loyees, and Yap 15th - July 29th, 1963, when the de f a c t o African ?opulation G a scounted. 3 e r e s u l t s of the t-zo counts vere subsequeatly analgaaced i a t o t o t a l population figures f o r 1963 by sinple ac!dition; since :he a s s u ? c l o c is of 20 growth i n the non-African populaticn betveen 1961 and 1 9 0 3 the cozs2quent t o t a l 1963 fLgure is l i k e l y t o be an underestimate. The African censcs co1lec:ed i ~ f o m a t i o non age in three broad age classes (1942 ~ n caf:?r, o r r o u ~ h l yunder 21, j e t - ~ e e n1918 and 19h1, or roughl:~21 t o h5, =.,, - " A befc~rt1913, o r rangtly L5 and over) , plus aczual year of b i r t h f o r those jorn i n 19L2 azd a f t s r .

The t o t a l count was 35 percent higher than the projected figure based on t h e 1950 sumey r e s u l t s , but t h e cecsus report concluded t h a t both external antd i n t e r n a l checks on the completeness of the count did not indicate an,y gross overcount i n 1963, and i n any case such underestimates of population s i z e a r e common before a f i r s t f lll census. The age data a r e probably unreliable, and the census report describes a i l information on personal c h a r a c t e r i s t i c s a s poor. - The 1969 Ce!nsus This cenras, held from 22nd-30th .August, 1969, w a s the f i r s t t h a t counted the e n t i r e population simultaneously and asked f o r exact age. Informatioa on children ever born and children sumiving t o women 15 and over, plus number of birzhs and deaths during the previous year, was collected from a l l urban households and a ten percent sample of rural households. Place of b i r t h and place of rzsidence 12 months age w a s recorded f o r sveryone . The quality of the r e s u l t s is again d i f f i c u l t to evaluate. No post-enumeration sumey was held. No particular problems were reported with the f i e l d siork. However, there is some reason t o suspect a s i g n i f i c a n t undercount r e l a t i v e to the 1963 census (as w i l l be discussed l a t e r ) and t h i s would not be surprising given the dramatic urban growth immediately a f t e r independenc~eand the norsally higher undercount t o be expected in urban areas. The quality of the f e r t i l i t y and s o r t a l i t y data is generally dubious; high proportions of women were apparently recorded a s not-stated v i t h respect t o f e r t i l i t y , while the data on deaths during t h e past year were so deficient t h a t they were discarded a t an e a r l y stage of analysis. Eowever, useful e s t i s a t e s of f e r t i l i t y and a c r z a l i t y can still be extracted fron the census inf omation. The 1974 S;mple Census A de facto sanple census w a s held between 16th August and t h e 7th Septenber, 1974. X sanpls of 10,000 w a s d r a m from a 100%house l i s t i n g exercise i n a l l l a r g e Urban .L-eas; Small Urban Areas and Tomships were e r m e r a t e d completely; and in the r u r a l areas a samplc of rdo *sic Areas (polling di.st r i c t s ) , each conraining an average of 3,000-4,000 persons, was taken from every d i s t r i c t . The o v e r a l l sampling fraction %xsexpected to be abaut I 4 pe!rcent , with a t o t a l sanple population of about 655,000. .A wide range of questions was asked, including children ever born and children surviving, b i r t h s durlng the Fast 12 months, ?lace of b i r t h and ?lace of rssidence 1 2 zionths ?reviously. T'fie quality of t h i s sanple census I s somewhat dubious.

The 1980 Census The l a t e s t cecsus was held from 15th August -7 t h September, 1980; p r e 1 h l n a r . y f i g u r e s have Seen published, but t h e f u l l census d a t a are still i n the d a t a processing s t a g e and w i l l not be a v a i l a b l e f o r another year o r so. A uidie range of questions, including c h i l d r e n ever born, c h i l d r e n surviving, births during the past 12 months, place of birth and place of residence 12 nonths ago, w a s asked on a sample b a s i s and a n e l a b o r a t e t a b u l a t i o n programme is being designed. Yo p a r t i c u l a r problems with the fieldwork have been reported. F u l l evaluation of t h e q u a l i t y of t h e census is of course still impossible. However, the prelitlinary r e s u l t s appear reasonable and c o n s i s t e n t . Small Scale S u n e y s X number of mall-scale demographic surveys have been held i n Zambia s i n c e 1963. The most notable among these a r e the surveys of the urban population i n t h e Copperbelt Towns and Lusaka, c a r r i e d o u t by t h e University of Zambia i n 1965 and 1968169 r e s p e c t i v e l y , and t h e survey of " I n t e r r e l a t i o n - s h i p s among Tnfant and Child Y o r t a l i t y , socio-economic Factors and F e r t i l i t y " i n Lusaka Cicy and a r u r a l area of Central Province c a r r i e d out j o i n t l y by 'LTNECX and t n e Zambian C s n t r a l S t a t i s t i c a l Office i n 1978179. These have provided i c t e r e s t i n g and o f t e n vsl.uable d a t a *uhich w i l l be r e f e r r e d t o as necessary. Internatio.na1 Yigration and Refugee Data Ln addition to t h e national sources of d a t a already mentioned, data on i n t e r n a t i o n a l s i g r a n t s and refugee movments can be gleaned from the censuses o f surrounding c o u n t r i e s and t h e r e p o r t s of t h e IM High Commission f o r liefuge~es(ONBCR) . Such d a t a a r e always t o be t r e a t e d with caution, but a r e indispensable. They w i l l b e r z f e r r e d t o and assessed as occasion a r i s e s . National ?opulation S i z e and Grovth 'mef i r s t actual enmeration of the African population i n Zambia ras carried ~ u zts part of the 1950 Demographic Survey, and gave a total of i.816 s i l l L o n f o r a i d 1950. This was however probably a gross undercount. {,'hen projected forvard ts s i d 1963 using the r a t e of 2.5 percent derived from survey f e r t i l i c p and mortality data-a r a t h e r high r a t e f o r the place and period, anti ix f a c t hig.her than the reported i n t e r c e n s a l grovth r a t e f o r 1963-1959--1: produced a t o t a l -mpulation e s t i m a t e o f 35 percent lower than t h e 1563 African census count.

However t h e r e still remains a puzzling incoasistency between the 1963-69 growth r a t e s and t h e o v e r a l l grovt5 f o r t h e period 1969-80. The gap jetween w l e and fenale growth r a t e s i n the f o r a e r period is s u b s t a n t i a l , (2.2 versus 2.6 percent) but almost disappears betveen 1969 and 1980 . (ignoring 1974), when they a r e 3.07 and 3.05 percent r e s p e c t i v e l y ; correspondingly t h e sex r a t i o drops from 99 t o 96. There is moreover a v e r y sharp rise i n t h e o v e r a l l rate of growth between t h e two periods, from 2.4 t o 3.1 percent; t h e 1963-69 rate of 2.4 percent a l s o does not a g r e e v i t h aa?ailable s o r z a l i t y , f e r t l l i t y and u i g r a t i o c d a t a f o r the 1960s which point t o a rars o f n a t u r a l Fncrease of arouod 3 percent and sodest n e t inmigration. The obvious explanation f o r these anomalies is t h a t e i t h e r t h e 1963 census was an overcount o r t h e 1969 census an a d e r c o u n t , r e l a t i v e t o each other. Of t h e t-do, it is most l i k e l y t h a t t h e 1969 census v a s an undercount r e l a t i v e to 1963. The p o s s i b i l i t y of an overcount in 1963 was considered i n t h e 1963 c.ensus r e p o r t i n connection v i t h t h e l a r g e s h o r t f a l l i n the population p r o j e c t i o n from i950, and t h e r e appeared t o be no reason t o suppose e i t h e r a c c i d e n t a l o r voluntary overcouncing t o any s i g n i f i c a n t degree. ? l e 1969 census on t h e o t h e r hand, d e s p i t e being t h e second census, had t o coatend v i t h the problems created by explosive urban grovth between I963 and 1.969; l a r g e t o m s and c i t i e s a r e n o t o r i o u s l y d i f f i c u l t t o enumerate completely a t t h e b e s t of t i m e s , and vheli immigration has been r e c e n t , r a p i d and s u o s ~ a ~ n t i a lthe l e v e l of *undercounting in urban areas, and hence i n t h e , =hole country a l s o , could w e l l r i s e s i g n i f i c a n t l y . Support f o r t h i s hypothesis comes from the Cecrease i n the o v e r a l l sex r a t i o from 99 t o 96, tnr f o r n e r b e i q a p r i o r i inore acceptable (given norsal sex d i f f e r e l i t i a l s i n z o r t a l i t y ,, a c o n a l - r a n g e sex r a t i o a t b i r t h , and net inmigration) and the change being i n t h e expected d i r e c t i o n i f t h e increased undercount is due t o omissions anong predor i n a n t l y mate urban migrants. X f u r t h e r piece of supporting evidence c ~ z e sfrom t h e 1969 age d i s t r i b u t i o n s f o r predominantly urban d i s t : r i c c s , uhich tend to shov an unexpected r e l a t i v e male d e f i c i t i n the young a d u l t age groups, t h e group u s u a l l y considered most prone t o a i g r a t e but a l s o the most li'&y to be missed i n enumeration. On t h e h o l e , t h e r e f o r e , it sems l i k e l y t h a t the coverage of the 1969 census ;-as i a v e r thari i n 1963. If the rate of growth betieen 1963 and 1969 were r e a l l y about 3 percent f o r both sexes1/ and the 1963 census a complete c.ount, t h e accual 1969 population *voulz have r e a c h e d 4 -22 m i l l i o n , compared t:o the enumerated L.06 n i l l i o n v f t h the s h o r t f a l l being about L58,000 o r 3.7 ;letcent; rhe m a l e undercount vould have Seen 5.1 percent 2nd the Fenale: 2.b ?ercent. It is of course unlikely that the I963 count was complete, so t h e n m b e r s omizced i n both 1963 and 1969 vould have been sonevhac higher.

The main features of population d i s t r i b u t i o n a r e clear. Large areas, particularly i n the Central-Westem and South-Eastern parts of the Tountry a r e almost uninhabited through lack of natural resources; they cover about 11 percent of the t o t a l national surface. Xuch of the remainder is very sparsely populated, with d e n s i t i e s of under f i v e inhabitants per km2. Small patches of very dense settlement occur around toms. There a r e also a few r e l a t i v e l y heavily populated rural-zones, notably along the l i n e of r a i l i n Central and Southern provinces (a zone of a g r i c u l t u r a l developnent as well a s close to urban centers), along the border betveen Eastern province and %zanbique/Xalawi (also a zone of good land and developing agriculture) , i n Luapula Province along rhe Zaire border and around Lake Bangweulu (good land and/or fisheries) and i n Vestern Province aloag the upper Zambezi p l a i n (again, r e l a t i v e l y favorable a g r i c u l t u r a l conditions); densities here a r e mostly i n the range of 10-50 1nhabi:ants per h2outside the toms. The *=pula and Zastern zones stand out i n particular a s both densely s e t t l e d and f r e e from urban influence. The other noticeable feature is the unusually even r u r a l settlement i n the ncrchern half of Sorrhern Province, though a t an intermediate l e v e l of density of about 2-10 inhabitants per h2. Clearly one of the nain determinants of population settlement patterns i n Zambia has been the a g r i c u l t u r a l resources available locally. Another, to be examined i n d e t a i l l a t e r , is the varying l e v e l of natural increase between p o ? ~ l a t i o ngroups, with f e r z i l i t y higher in che s o r e densely populated eastern half of the country than i n the eaptier western half. A third is t h e development of the aodern communications net-rork, s o s t r~otablythe old l i n e of r a i l from Copperbelt t o Livingstone but also the main a r t e r i a l roads north and e a s t ; these have stimulated both agricultural and urban development. The fourth (which is c l e a r l y interrelated with the t h i r d , and possibly the most Fsportant i n recent years), is urbanization, which has not only concentrated a substantial proportion of the population i n t o a few large urbau centers, but has also stimulated r u r a l settlement around the t o m s , v i t h t h e i r large food narkets and good corrrmunications. Zambia is one of the most massively urbanized countries i n Sub-Saharan Africa, wicn L3 percent of the population living i n urban centers at the t h e of the 1980 census. This urbanization is characterized by t-ao s t r i k i n g features; f i r s t , w p l o s i v e urban growth since independence, now slzckening oi f ; and second, concentr;rtion i n large, truly urban, towns founded on strong economic bases of nining, industry, o r c e n t r a l government administration.

If 1974 is taken into consideration the decrease seems to have been auch sharper i n the late 1970s than i n the e a r l y 19709, and t h i s is quite plausible given Zambia's economic h i s t o r y over the past 15 years; however the uncertain q u a l i t y of the 1976 d a t a precludes assurance on this point. It is clear, none the less, that large tova growth has been much reduced o v e r a l l ; indeed i n four of the seven Copperbelt t o m s , namely ChingolLa, Xufulira, L~lanshyaand Chililabcmbve, grovth r a t e s are now down to, o r below, l i k e l y r a t e s of n a t u r a l increase, inplying t h a t n e t immigration t o these 1:owns has ceased.

Table D.9 Province 1969 1974 1980 (Yew) Csntral (Sew) Lusaka Capperbel t Eastern Luapula Northern Southern Western Yortthwestern Total Zambia 8 57 75 Clearly the reclassification has been on an enormous scale, wlth only 8 SUTs in 1969 but 75 in i986, and is a major factor in the recorded grovth of %J'T population; c l e a r l y also, part of the reason f o r the higher SUT population growth r a t e i n 1969-74 than f n 1976-80 was the l a r g e r amber of reclassified l o c a l i t i e s added in the e a r l i e r period.

Bowever ve can examine the growth r a t e s a f t e r reclassi.fication of those reclassified i n 1974, and also the grovth rates of the eight small towns already so categorized i n 1969.

I:! general, however, growth has been very high i n the l a t e 1970s. Moreover, out of the eight towns so c l a s s i f i e d since 1959 (which include a l l the l a r g e s t SUTs) the growth r a t e iocreased a f t e z 1976 f o r s i x of them. Again, the 1974 data cannot be considered absolutely r e l i a b l e , but it seems l i k e l y t h a t overall, the observed slackening of grovth i n the t o t a l SUT population a f t e r 1974 is due to a decrease i n the numbers of reclassifications rather than decelerating growth of the population u i t h i n the townships. Trends u i t h i n the small t o m s thus present an interesting contrast to those u i t h i n the l a r g e towns. In the SUTs grovth is generally much higher, and may w e l l have accelerated i n the late 19709, w h i l e in the LUAs growth is r e l a t i v e l y lov and appears to have decelerated Fn the late 1970s. The former have evidently grown chiefly through inmigration, v h i l e i n the l a t t e r natural increase has a l s o been important, and indeed may nov be the dominant component of grovth i n some. These trends a r e no doubt the mixed r e s u l t of goverument policies to decentralize industry and administration into smaller centers and of declines i n nining and i n d u s t r i a l d e v e l o p e a t i n the l a r g e toms.

Conversely, the percentage of native-born l o s t is a measure of the propensity t o outsigrate from a province. The patrern here is rather varied. The heaviest losers a r e Sorthem and a s t e r n , each with around a quarter of t h e i r native-born l o s t , followed closely by Sorth Western and Luapula, each wich a l o s s of just over a f i f t h . The l i g h t losers are, a s expected, Central,, Copperbelt and. Southern, but also Vestern. Evidently the urbanized line-of-.rail provinces have retained t h e i r population a d the r u r a l off-line!-cf-rail population have l o s t t h e i r s , the exception beirg Western which apparenrly has rather an i m o b i l e population. This is again much as expected from the urban data. The f u l l pattern of interprovincial migration, shorn in Appendix Table X.D.6, holds few surprises. Briefly, Copperbelt a t d Cerrtral a r e the magnets for all other provinces, with Capperbelt the more a t t r a c t i v e to Xorzhwes,t e r n , Luapula and fiorthern, vhile Central is nore a t t r a c t i v e t o Eastern and Southern, and there is l i t t l e difference between the two f o r l e s t e r n , vhich is most a t t r a c t e d to Southern; Copperbelt also a t t r a c t s s i g r a t i o n from Cantral. These flovs follow the normal "gravity" pattern of migratia~n,wnereby the nearest a t t r a c t i o n s a r e preferred. .As a summary, Table D.12 belov shows the nmber and percentage of t o t a l pa~pulationborn i n and resident i n each province with the net gain/ loss. .Qain the massive nigratory gains of Copperbelt and Central, t h e minor gain of Southern, the substantial losses of Xorthwestern, Luapula, Xorthorn and Eastera, and the m a l l e t l o s s of Western, can be c l e a r l y seen. These data of course shov only the situation i n 1969, a f t e r the period o f m s s i v e urban growth and r ~ r a lnear-stasis o r decline.

The tuo provinces ' d t h lowest, indeed negative, growth during t h e 1963-69 period were Xorthern and Luapula; Uesterb s u f f e r e d decreasing growth a f t e r 1969. A l l these trends r e f l e c t i n i t i a l l y high rural-to-large town migration from every r u r a l province but Cestern, which then declined s i r h the d e c l i n i n g mining and i n d u s t r i a l s e c t o r s ; consequently the growth of t h e highly urbanized provinces f e l l while t h a t o f t h e r u r a l provinces, with t h e i r developing mall towns, picked up.
