research indicates that many sami became reindeer herders in the early 17th century , as a response to a population crisis ( 9 ) . this transition coincided with the swedish state 's increased interest in spmi , the distant regions of the north which were the sami 's traditional lands . courts were held annually , market places were built , and the first printed books in the sami language appeared ( 10 ) . further interest in the area was stirred in the late 17th century by the discovery of silver , but the mining epoch lasted for only 50 years . the sami remained very isolated , not only because of their economy and culture but also because of the great distances between households and the intense cold of the region for most of the year . at the end of the 17 century , the state also tried to encourage settlers to move to the area , offering free land , and 15 years free from taxes . this had , however , a limited impact on in - migration , a trend that did not change until the mid-18th century . during the following 100 years , the ethnic balance in spmi changed , turning the sami into a position as minority in their own lands . omran 's essay on the epidemiological transition , modeling societies change from high mortality due to infectious diseases to low mortality caused by chronic diseases , has had a great impact on the public health community and stirred research in a variety of disciplines ( 12 , 13 ) . indigenous peoples were not mentioned in his work , but few researchers would dispute that the indigenous populations of the world experienced demographic transitions much later than non - indigenous populations . however , although an indigenous demographic or health transition is generally acknowledged , due to lack of longitudinal data , it is rarely examined ( 14 , 15 ) . the main source material used for the present study is a set of data files from the demographic database ( ddb ) at ume university , one of the world 's most information - dense historical population databases . a recent addition to the ddb are 18th and 19th century parish records from spmi . the longitudinal database includes every individual in the parishes during the period when the area was colonized , largely by swedish settlers , and the sami population changed from a majority to a minority . the source material separates the sami and the settler populations and contains information on , for instance , sex , age , cause of death , migration , and fertility . each individual can be followed from the cradle to the grave allowing the reconstruction of life biographies and family composition based on ethnic categorization ( table 1 ) . working sample and missing cases individuals born in 17501895 . because data quality is poor in the earlier years , the time period has been restricted to 17501895 . only infants born within the study area and with a known birth day have been included . infant mortality is calculated by the number of deaths within the first year of life during a time period divided by the number of live births during the same period . when calculating infant mortality and making comparisons with swedish national data , 10 year intervals were used ( 16 ) . the risk of infant mortality is modeled as a cox proportional hazard model with ethnicity , sex , parity , birth season , and birth period as the explanatory covariates . 1 ) . map of sweden , including the parishes of jukkasjrvi , jokkmokk , and fllinge . sami live in four countries , speak nine different languages , and are diversified by reindeer - herding techniques , social organization , and economic resources . until the early 19th century , sami land rights were legally protected , but then a more repressive state policy replaced the sami traditional division and use of land with a national administrative system ( 17 ) . the present study includes three parishes where sami were in a great majority around 1750 . the church registers of jukkasjrvi and jokkmokk in the north sami area contained both sami and swedish settlers , whereas fllinge sami parish in the south sami area was an administrative construction exclusively for the indigenous population in the area . the magnitude and timing of colonization differed between the parishes . in the northernmost parish of jukkasjrvi , sami were in majority throughout the period 17501900 . until 1850 , there are around 400 non - sami and 1000 sami , and both groups experienced a population increase from 1880 , settlers more than the indigenous . we believe that the parish of jokkmokk is more representative of the sami parishes in general , where an ethnic majority shift occurred around 1830 , moving in a frontier wave from the south to the north . in the parish of fllinge , the ethnic majority shift came earlier : from the late 18th century , there were more non - sami than sami in the area , and the change accelerated so that at the end of the period there were almost 10 times as many swedes as sami . previous research has to a large extent exclusively counted the reindeer herding nomads in the sami group . there was , however , an ethnic complexity in the north already during the early stages of colonization , and not all sami were nomadic reindeer herders ; large groups were hunters or farmers , and during the period , many sami took up residence in settlements , becoming settlers but still sami , sometimes recorded as  sami - settlers [ lappnybyggare ] in the parish registers . all these groups are included as sami in our study , resulting in a sami population larger than normally stated . this has been done to create a more  in situ-oriented demography ( 18 ) . we have combined the ethnic markers in the sources using a system designed by the historian gabriella nordin in her dissertation on marriage patterns in spmi 17501900 and also presented in skld and axelsson ( 5 , 11 ) . a complementary source of information about infant mortality is the annual reports of the district physicians in the area . however , the doctors were not well acquainted with the conditions among the sami , and the reports often give laconic and judgemental descriptions of sami health . previous studies of sami mortality have revealed considerably higher rates from 1750 to1900 compared with non - sami , both in spmi and in sweden generally ( 4 , 5 , 19 ) . by contrast , the second half of the 20th century shows no ethnic mortality differences ( 3 ) . this is consistent with the occurrence of a delayed indigenous demographic and epidemiologic transition ( 20 ) , and because infant mortality is one of the early indicators of intensified change , our study aims to find evidence for declining imr among the sami before 1900 that could be interpreted as a forerunner of a general transition . long - term infant mortality trends are analyzed to compare sami and non - sami groups in the three parishes.using both northern and southern sami areas , the cultural complexity of the sami society is recognized . sex differences and seasonality are included parameters that are interpreted in terms of the varying work intensity of the reindeer nomads . parity , causes of death , and change over time are additional variables that complete the study together with an estimation of the impact of health care programs . the results are discussed from the perspective of data quality , methodological issues , and the general demographic transition in sweden . the sami have lived in spmi for thousands of years and have learned to adapt to the extreme conditions there . nevertheless , the nomadic sami lifestyle , the hazardous character of reindeer herding , and a shifting food resource resulted in a high mortality , including infant mortality . the sami were devoted parents with strong emotions and traditions attached to their children , and had developed customs for reducing risk during pregnancy , delivery , and child care . the child was believed to be endangered by evil spirits and other threats , and a newborn child was put in a skin from a newborn reindeer calf , with a piece of steel close to the infant to protect it ( 22 ) . it is universally reported by the clergy , physicians , travelers , politicians  and later also expressed by the sami themselves  that sami children were breast - fed for at least 2 years , and sometimes for as long as four years . during the first days after birth , before the mother produced milk , the infant was given a piece of sugar or reindeer fat in a small napkin . some sami women consumed alcohol during pregnancy but not during the last days before birth giving . however , when the infant was born , the woman was encouraged to drink quite a lot of alcohol ( 22 ) . the non - sami settlers were mostly from other parts of sweden , but sometimes from finland or norway . colonization was promoted by the state from the late 17th century , but the great explosion of in - migration occurred in the second half of the 19th century , when mining , railroads , and improved agricultural techniques offered new opportunities . from the mid-18th century , the swedish health care system tried to reduce the very high infant mortality in the country . in stockholm and other urban areas , sometimes more than half of the newborn children died within their first year of life . medical instructions were published concerning the care of infants , and district doctors were employed , even though in the 1870s it was still a rare event for someone in northern sweden to have a visit by the doctor ( 23 ) . in earlier times , the clergy were given responsibility for health care , but during the 19th century they became less and less involved . they were officially released from health duties in 1830 , and after this , their participation in medical issues in the parish was greatly reduced , although many clergy continued to assist with medical advice . from this time , midwifery services increased , although economic difficulties caused many parishes to resist official requests to employ a midwife ( 24 ) . in the early 19th century , the northern parishes had among the highest infant mortality in sweden . the imr declined over the 19th century , as a result of improved hygiene , and increased breast - feeding . in many places in sweden , instead , there was a widespread culture of artificial feeding , where undiluted and unboiled cow milk , often sour and of bad quality , replaced breast - feeding . different sorts of diarrhea were common in those areas , especially during the warm summer months . the combination of hard agricultural work that often prevented mothers from breast - feeding their infants , and the difficulties in preserving fresh milk , resulted in repeated mortality peaks from june to august . previous research has shown that high levels of artificial feeding of infants lead to higher mortality during the summer months . nevertheless , many areas in northern sweden experienced a great reduction in infant mortality during the 19th century . in some parishes , it dropped from over 50% to below 18% 50 years later ( 23 ) . swedish observers in the 18th century believed that lapland , as spmi was then known , was one of the healthiest places someone could live . it was thought that the fresh air guaranteed a long and strong life . although some clergy were afraid that the nomadic life that began soon after the birth was harmful , as were the drinking habits of the women , the sami were generally described as healthy : children were given frequent baths and infants were breast - fed for several years ( 25 ) . it was not until hellstenius in 1884 published an article on infant mortality in the counties of jmtland and hrjedalen , including the south sami area , that the extremely high infant mortality among the sami was revealed . however , hellstenius offered no explanation other than vague ideas about racial differences . later , wahlund showed a similar infant mortality among sami parishes in the northern area , twice as high as the settlers . children and adults showed no corresponding increased mortality ( 26 , 27 ) ( fig . sami infant mortality in jukkasjrvi , jokkmokk , fllinge , and sweden in 17511895 . registration before 1780 is often incomplete and the imr is unreliable . at the end of the 18th century , sami infant mortality was at the same high level as the rest of sweden , and occasionally even higher , but when the imr declined generally in sweden from 1810 , the sami in jukkasjrvi and jokkmokk stayed at high rates . the sami parish of fllinge shows considerably lower rates than the sami in the other two parishes , and until 1850 sami infants in fllinge had much lower mortality than in the rest of sweden . the trend appears to continue with only six infant deaths of 93 births during the period 18501895 . due to the low overall number of births and deaths , we have excluded 10 year averages for fllinge parish ( table 2 ) . infant mortality ( per 1000 ) in jukkasjrvi , jokkmokk , and fllinge in 17501899 source : demographic database , ume university . there is a general trend of decreasing sami infant mortality in 17501899 . in the northern parish of jukkasjrvi , sami have consistently higher imr than the rest of sweden , but the difference decreases over time . until 1850 , they also have higher rates than the non - sami in the parish , but during the second half of the century , the situation is the opposite . the non - sami in jukkasjrvi experience increased infant mortality over time . before 1850 , the non - sami in jokkmokk also have lower imr than sweden until the mid-19th century . they have an increasing imr trend over time , nevertheless their rates are lower than the sami throughout the period . in fllinge , there are insignificant imr differences between sami and non - sami , and both groups are well below the swedish average . there is an excess infant mortality for males in all three parishes , and for both sami and non - sami ( except for non - sami in fllinge ) . male and female infant mortality ( per 1000 ) in jukkasjrvi , jokkmokk , and fllinge 17501899 source : demographic database , ume university . the higher male imr is significant for both sami and non - sami in jukkasjrvi and in jokkmokk , but in fllinge only for sami . there is , however , no reason to believe that these differences have any explanatory value for the demographic transition in spmi . it was often claimed that sami families were smaller than non - sami families in the area ( 28 ) . this was often based on an assumption that a large family was an obstacle to the nomadic life of the reindeer herders ( table 4 ) . infant mortality ( per 1000 ) after parity in jukkasjrvi , jokkmokk , and fllinge 17501899 source : demographic database , ume university . in all three parishes , sami infants born as child number five or more suffered from the highest risk of dying . although we can not control for the number of older siblings that were actually alive , it seems clear that large families were less able to avoid infant mortality . the mothers who gave birth for the fifth time or more were also older than those giving birth for the first time . the health status of the mother is an important determinant of infant survival , especially during the first week . among the sami , first - born infants had the second largest risk of dying , whereas among the non - sami they experienced the greatest risk . the settlers may have lacked the well - developed traditional knowledge needed for dealing with the cold climate and other risks specific to the northern inland area . both ethnic groups in all parishes had the lowest risks for mortality for infants born as number two , three , or four in the birth order of the mother . the period of study includes great social , political , economic , demographic , and environmental changes . due to the unreliability of the data during the 18th century , the cox regression analysis is based on results from the period 18001899 ( table 5 ) . cox regression of infant mortality in jokkmokk , jukkasjrvi , and fllinge , 18001899 note : e is the relative risk , p is the p - value for each parameter in the model . the results show geographical differences between the three sami groups . in jokkmokk with an ethnic majority shift around the 1830s , this is also the only parish with the highest mortality risk among the first born infants in 18501899 . the northern parish jukkasjrvi experiences a dramatic shift from twice as high sami infant mortality in18001849 to slightly lower imr compared to the non - sami during the second half of the century . the more balanced the ethnic proportions became , the less differences occurred in infant mortality . in the southern parish of fllinge , sami were a minority from the 18th century , but nevertheless they showed higher imr over the entire period . generally , a modest male excess mortality is found and less risk for parity 24 . there are no noteworthy seasonal differences , except in fllinge where higher imr appeared among infants born during the winter months january to march . the sample from this parish is too small to include separate analyses for different periods of the 19th century . it was often claimed that sami families were smaller than non - sami families in the area ( 28 ) . this was often based on an assumption that a large family was an obstacle to the nomadic life of the reindeer herders ( table 4 ) . infant mortality ( per 1000 ) after parity in jukkasjrvi , jokkmokk , and fllinge 17501899 source : demographic database , ume university . in all three parishes , sami infants although we can not control for the number of older siblings that were actually alive , it seems clear that large families were less able to avoid infant mortality . the mothers who gave birth for the fifth time or more were also older than those giving birth for the first time . the health status of the mother is an important determinant of infant survival , especially during the first week . among the sami , first -

sami in the area show increased imr over time , and did not follow the decreasing imr in sweden from the 1820s . the indigenous people of northern sweden experienced a delayed process , and at the end of the 19th century , their imr were still above the national average . on the other hand , the trend shows decreasing imr , and we know that the gap between the sami and the rest of sweden was closed around 1950 . other indigenous peoples of the arctic still have much higher mortality rates , and an imr below 100 was achieved only after 1950 in most countries ( 29 , 30 ) . between 1910 and 1939 , the native people in canada had an imr between 120 and 205 ( 31 ) . serning reported remaining ethnic imr differences in jukkasjrvi and jokkmokk for the period 19301948 , but they were rapidly decreasing ( 22 ) . and , from the 1960s , there are no significant mortality differences between sami and non - sami in the area ( 3 ) . therefore , the first half of the 20th century is crucial for our understanding of the imr transition in spmi , and hence for our understanding of the sami demographic , epidemiologic , and health transitions . brndstrm ( 23 ) asked if there were reasons to believe that the sami practiced birth control . contemporary observers claimed that sami women gave birth to few children , rarely more than five or six ( 31 ) , even if they married at early ages ( 11 ) . by limiting family size , they may have avoided the increased risk associated with higher order births , and by concentrating births in the seasons with lower risk , they may have improved survival . cultural responses to infectious diseases and the use of a so - called komse , a small wooden boat box where infants were kept almost constantly for 1 or even 2 years ( 32 , 33 ) helped in the care of the newborn children . the traditional nomadic life style is important for our understanding of sami infant mortality ( 25 ) , but there is no reason to believe that hard working conditions caused the sami women to stop breast - feeding their infants , as was often the case in other contexts ( 34 ) . reindeer herding was an extreme form of living , and the social organization did not offer any assistance . sami women either rejoined the continuous travel with the reindeer only a couple of days after giving birth ( 31 ) or were left alone with the child in a hut ( 22 ) . until the mid-19th century , the sami imr was considerably higher than the non - sami in the area , even though extensive breast - feeding prevented infectious diseases and nutritional deficiencies . we can note cultural differences within spmi , where the south sami joined the low imr of the district of jmtland , whereas the northern parishes remained at higher levels . however , there is no evidence that medical interventions played any significant role in the reduction in infant mortality . the sami rarely had any contact with the district physicians , and midwives were not appointed in the northern parishes until the late 19th century . kertzer and fricke ( 35 ) take a cultural approach to demographic behavior , arguing that from an anthropological perspective , the concept of agency must be given more prominence . they emphasize a cultural sphere that is interwoven with , both shaping and being shaped by , political and economic institutions as well as by kinship and other social organizational structures . the sami population has slowly increased since the 18th century and onwards , and the previous general opinion that the sami were a dying race has been proven to be mistaken . it is the sami culture , and not the sami race , that is under threat today ( 36 ) . but the path to this point has been long and winding , including great improvements in life expectancy . infant mortality was a difficult obstacle to overcome , and the final breakthrough did not occur until the 20th century . the authors have not received any funding or benefits from industry to conduct this study .
the study deals with infant mortality ( imr ) that is one of the most important aspects of indigenous vulnerability.backgroundthe sami are one of very few indigenous peoples with an experience of a positive mortality transition.objectiveusing unique mortality data from the period 17501900 sami and the colonizers in northern sweden are compared in order to reveal an eventual infant mortality transition.findingsthe results show ethnic differences with the sami having higher imr , although the differences decrease over time . 
 there were also geographical and cultural differences within the sami , with significantly lower imr among the south sami . generally , parity has high explanatory value , where an increased risk is noted for children born as number five or higher among siblings.conclusionthere is a striking trend of decreasing imr among the sami after 1860 , which , however , was not the result of professional health care . 
 other indigenous peoples of the arctic still have higher mortality rates , and imr below 100 was achieved only after 1950 in most countries . 
 the decrease in sami infant mortality was certainly an important factor in their unique health transition , but the most significant change occurred after 1900 .
