The overall income inequality decrease that Vietnam experienced from the early 2000s suggests that its growth has been accompanied by equity extending beyond poverty reduction [@Benjamin2017].
On the other hand, Le et al. [-@Le2021] suggest a slight increase in overall income distribution from 2010-2018.
At the same time, the ones most affected by poverty through welfare inequalities stay unaltered, as do largely the primary factors accompanying it:
There is severe persistent poverty among ethnic minorities in Vietnam [@Baulch2012],
concomitant with low education and skills, more prevalent dependency on subsistence agriculture, physical and social isolation, specific disadvantages which become linked to ethnic identities and a greater exposure to natural disasters and risks [@Kozel2014].
Economic inequality and poverty in Vietnam thus underlies an intersectional focus, between ethnic minorities, regional situations, rural-urban divides and gendered lines,
one which exogenous shocks can rapidly exacerbate as the example of the COVID-19 pandemic has recently shown [@Ebrahim2021].

Ethnic minorities in Vietnam are distinctly over-represented in poverty in addition to often being left behind in the development process, not least due to being extreme representatives of the economic situation of Vietnam's rural population.

While the quantitative evidence for impacts of such shock events are relatively sparse, Jafino et al. [-@Jafino2021] lament the overuse of aggregate perspectives, instead disaggregating the local and inter-sectoral effects to find out that flood protection efforts in the Mekong Delta often predominantly support large-scale farming while small-scale farmers can be harmed through them.
They find that measures decrease the aggregate total output and equity indicators by disaggregating profitability indicators into inundation, sedimentation, soil fertility, nutrient dynamics, behavioral land-use in an assessment which sees within-sector policy responses often having an effect on adjacent sectors.

Adaptation during these catastrophic events reinforces the asset and endowment drivers of non-shock event times,
with impacts levels often depending on access to non-farm income sources, access to further arable land, knowledge of adaptive farming practices and mitigation of possible health risks such as water contamination [@Son2020].
Karpouzoglou et al. [-@Karpouzoglou2019] make the point that, ultimately, the pure coupling of flood resilience into infrastructural or institutional interventions needs to take care not to amplify existing inequalities through unforeseen consequences ('ripple effects') which can't be escaped by vulnerable people due to their existing immobility.

Inequality in Vietnam, then, while generally decreasing across the whole population distribution,
Inequality in Vietnam, then, is slowly rising across the whole population distribution,
runs the danger of increasing due to schisms opening within individual sectors of vulnerable groups.
Rural populations experience a trend towards increasing inequality within their sector,
driven primarily by the social exclusion and geographic isolation of ethnic minorities,
