“…Zambia should, therefore, find a means of reducing the undercount of this particular age group by improving the data collection systems. This finding is consistent with previous studies that found low sex ratios among younger working ages (20 to 35 years) in most populations of the world (Phillips et al, 2003;Smallwood & De Broe, 2009;Dyson, 2012). The most common reason that has been advanced to explain this phenomenon is that young men and women are geographically mobile in search of employment opportunities and are mostly missed in census enumerations because they are habitually absent from their dwelling places, resulting in the under-enumeration of this particular age group.…”

The sex ratio question has been an area of growing interest in population dynamics, especially in developing countries with respect to the issue of missing women, but few studies have examined this in sub-Saharan Africa. Both at birth and in the general population, sex ratios follow an expected demographic pattern in the absence of the interference of historical events affecting either males or females in a population. In Zambia, an unexpected demographic pattern of sex ratios is exhibited in census and survey data. This study used data from censuses and surveys conducted from 1969 to 2014 to examine variations in sex ratios in the Zambian population. It was found that sex ratio imbalances were largely due to data deficiencies due to age misreporting and under-enumeration. A consistent under-enumeration of young adult males in the 20–34 years age group was found. A systematic pattern of high sex ratios, above 100, for ages 40+ was found, represented by synthetic cohorts traceable from the 1969 census, progressing to the 2000 census and phased out in the 2010 census. Extremely high adult male mortality was found in 2010 in the 35–59 years age group, primarily attributable to HIV/AIDS. Understanding the demographic pattern of sex ratios in a population is relevant for policies to improve the quality of data collection systems, and socioeconomic development planning, for the young age group population, which is prone under-enumeration.

“…General findings from around the world relating to this type of analysis 6 elicit similar patterns between census data and demographic age-sex patterns to those depicted in Figure 1. When data is further disaggregated, by ethnicity for example 7 8 the discrepancy between sex ratios at younger ages is even more evident.…”

“…11 The sex ratio lower than the national average might be due to the reason that majority of the families in our population are migrated and migratory population are predominantly male populated, as employment is the major reason for migration, and slums constitute manual labor migratory population, formed by the males. 12,13 Literacy rate in our community is 76.9% whereas the national rate is 74.04%, and in overall slums is 84.11%. 4,14 The difference of 8 percentage points between national level literacy rates in slums and our study population might have been due to greater migratory nature (63%) of our community.…”

Background: Rapid urbanization has led to the increase in a group of people called ‘Urban poor’ dwelling as a community in ‘Slums’, worldwide. Slums manifest deprivation that transcends income poverty. Hence, we conducted this Community-oriented primary care (COPC) exercise, to give medical students a greater understanding of the situation of individual patients in the slum and to formulate a community diagnosis.Methods: The current study was done at Tyagaraj Nagar Jhuggi in the South district of New Delhi, during Community-oriented primary care (COPC) exercise of undergraduate medical students in their 4th semester over a period of 20 days, using a predesigned proforma for collecting data on health events and determinants of health, from families. 35 households were chosen by systematic random sampling.Results: Out of 179 community members studied, 33 (18.43%) were afflicted with morbidity, which consists of common cold with cough, generalized body pain and joint pain. The sex ratio was found to be 826, literacy rate was 76.9% in the study area, 44.11% of the households were having sanitary latrines owned by them, 68.6% had a closed drainage system 63% of the families used clean fuel for cooking and unmet need of contraception was 85% among eligible couples.Conclusions: Investments in women’s access to various contraceptive preferences are urgently needed to help increase the contraceptive prevalence rate. Health Education and awareness campaigns on prevention of potential mosquito, fly breeding sites, hand hygiene, avoidance of firewood as fuel, establishing smoke outlet and solid waste management should be arranged.
