Women Empowerment and socioeconomic inequality in immunization coverage: a case study of Zambia
… namely, full, partial and no immunisation. Concentration indices are used to assess inequality in full, partial and no immunisation coverage as well as in the intensity of immunisation coverage. Briefly, a positive concentration index means that immunisation coverage is pro-rich as richer …

Socioeconomic inequalities in the use of skilled birth delivery during childbirth in Ghana: a decomposition model
… Health Survey (GDHS) using a decomposable health concentration index. Concentration index (CI) and concentration curves were employed to measure the magnitude of socioeconomic inequality in the use of skilled birth attendants during child delivery. The concentration index was decomposed to …

Socioeconomic inequalities in non-communicable diseases in South Africa
… (NIDS) were used. The methods used include the concentration curve, concentration index and decomposition analysis to assess the drivers of socioeconomic inequality in NCDs and some causes of NCDs including smoking, obesity, high blood pressure; use of screening services and effective coverage …

Determinants of economic growth In Sub-Saharan Africa: decomposition of exports and imports
… export components, import components, export concentration index, capital and labour force as variables of analysis. The results of fixed effects estimations show that both exports and imports contribute significantly to economic growth. On a specific level, growth in raw material exports, and …

The impact of smoking on individual health expenditures: a case study of Namibia
… costs and total out of pocket (OOP) payments. Concentration curves and indices are estimated for all three variables as well as for smoking intensity and smoking prevalence. Further, three Tobit regression models are run to examine the associations of the different healthcare costs with smoking …

Socioeconomic related health inequalities in South Africa
… health outcomes, self-assessed health, body mass index and depression, to test for the potential effects of attrition bias on parameter estimates. We test using the attrition probit and Becketti, Gould, Lillard and Welch (BGLW) tests, which are two well-known tests for attrition bias in panel …

Explaining the socio-economic inequalities in child immunisation coverage in Zimbabwe
… coverage in Zimbabwe were assessed using concentration curves and indices. A positive (negative) concentration index indicates immunisation coverage concentrated among the rich (poor). The concentration index was decomposed to identify how different variables contribute to the …

Socioeconomic inequities of malaria prevalence in under-five children in Ghana between 2016 and 2019
… region and a few others. Our study applied the concentration indices and curves to assess socioeconomic inequalities in malaria prevalence among under-five children and decomposing the concentration index to identify contributing socioeconomic factors. Results The 2019 concentration index was …

DEVELOPMENT AND EVALUATION OF TECHNIQUES FOR HYDROCLIMATOLOGICAL CHARACTERIZATION
… a stationary climate. First, I devise a temporal concentration index (TCI) for quantifying the clustering of precipitation events in time and compare it to other indices used to quantify the temporal organization of precipitation. TCI can resolve both seasonal and non-seasonal clustering of …

Investigating family social capital and child health: a case study of South Africa
… inequalities were assessed using the concentration index. To assess the relationship between family social capital and child health, regressions models were fitted using a selected set of explanatory variables, including an index of family social capital. Child health in this study was …

An investigation into out of pocket health expenditure in India
… inequality in CHE in India. Rank-dependent concentration curve and concentration indices have been estimated. The concentration curve shows that CHE is more concentrated among the rich in India. Keeping in consideration the impact of measurement scale of the variable, the standard …

Socioeconomic inequalities of childhood obesity in South Africa
… the extent of SE inequalities in obesity using concentration index (CI). The study also assesses the determinants that underpin these inequalities using decomposition analysis of the CI. Overall, the positive CI from the results indicates that the burden of obesity is more concentrated among the …

The Universality of Intrinsic Flattening in Extragalactic Stellar Disks
… physical parameters – total stellar mass, concentration index, total HI mass, mass of the central mass concentration (CMC), and circular velocity – are also investigated. We find that: (i) the intrinsic flattening of spiral galaxies is ⟨𝑐/𝑎⟩ = 0.130 ± 0.002 (stat) ± 0.034 …
