Likewise, we consider future changes in Nepal’s tariff advantages over competitors by including the 2026 tariff rates available from the tariff reduction schedules of trade agreements that are currently in force.The analysis identifies, at a detailed product and market level, for all potential partners, where losses are expected to be significant. The findings are contrasted with the untapped trade potential estimated for 2026 – a figure calculated by tailoring the ITC export potential methodology to the LDC graduation context. (...) A description of tariff changes to be expected upon graduation is included in Section II, Section III presents the estimated effects of graduation-related tariff changes on exports and Section IV contrasts the effects found with export growth opportunities.

Sub-Saharan Africa had the second largest share of intra-regional migration (63 per cent). By contrast, Central and Southern Asia had the largest share of its diaspora residing outside the region (78 per cent), followed by Northern America (75 per cent) and Latin America and the Caribbean (74 per cent).
8. Women and girls comprise 48 per cent of all international migrants
In 2020, the number of female migrants slightly exceeded that of male migrants in Europe, Northern America and Oceania due in part to the higher life expectancy of women among long-term migrants and to the increasing demand for female migrants for care-related work. By contrast, in Northern Africa and Western Asia as well as in sub-Saharan Africa, the number of male migrants significantly exceeded that of female migrants due to a greater demand from male-dominated industries and to the preponderance of temporary work visa and labour contracts targeting male workers.
9. (...) The policy domains with the highest levels of adherence were “cooperation and partnerships” and “safe, orderly and regular migration” for which more than three quarters of Governments reported meeting or fully meeting the criteria for indicator 10.7.2. By contrast, the domains covering “migrant rights” and “socioeconomic well-being” had the lowest proportions reporting a wide range of policy measures: 55 per cent and 59 per cent, respectively.

Around 22 million international migrants under 20 years of
age reside in least developed and developing countries,
accounting for 62 per cent of the total migrant population
under the age of 20. In contrast, some 13 million migrant
children and adolescents reside in developed countries,
representing approximately 38 per cent of international
migrants under 20 years of age.
(...) In Asia and Oceania there are 82 and 96 female migrants for every 100 male migrants under 20 respectively, while in Europe there are 93 female migrants for every 100 male migrants. In contrast, in Africa there is virtual parity, that is, for every 100 male migrants there are 101 female migrants under the age of 20.

Table 1 shows that there are distinct contrasts in age and sex composition in various regions of Europe. (...) The cold war era accentuated the contrasts. Today, many of them have grandchildren who never lived in a communist society. (...) He traces the contrasts back to the late Roman Empire, suggesting that Southern Europe reflects early Muslim influence.

10 Relationship between dimensions of safety signs and distance of observation
The relationship between the greatest distance from which the safety sign is legible and conspicuous in shape and
colour and the height of the safety sign together with the distance factor Z is given by the formula
h = I / Z
were h and I have the same units (see Figure 21).
(...) Transilluminated exit signs and directional escape route signs with average luminance of the contrast colour
greater than 500 cd/m2 will double the factor of distance and therefore the observation distance.

contrasts with the black surrounding line however is not contrasting with the grey
background. The provision is ambiguous since it stipulates that the centre should be
white or contrasting however fails to specify with what it should be contrasted.
