To better respond to
the challenges of demographics, attaining
departmenthood, and the expectations of the people
Thematic public report
Mayotte became a French overseas department in 2011, in response to the long-
standing, repeated aspirations of the people of Mayotte and their elected representatives. In
2016, the Court1 noted the inadequate preparations for this institutional reform, which,
although unrelated to the crises in the archipelago, did not lead to resolve them. The central
government and the department are struggling to outline sustainable development prospects
for Mayotte, while difficulties are getting worse.
The first challenge facing the Mayotte archipelago is demographics. The population
growth rate has accelerated over the past decade, reaching 4% in 2017. There are many
indications that its population, estimated at 289,000, is actually greatly underestimated. This
uncertainty is detrimental to the reliable measurement of the archipelago’s
characteristics, as well as to the proper dimensioning of public policies.
The archipelago’s population is projected by INSEE to reach between 440,000 and
760,000 inhabitants by 2050, the main determining factor being changes in migratory flows. In
the highest hypothesis, the population density would increase to more than 2,000 inhabitants
per km² (compared to 774 today), i.e., the highest density in France, after Paris and its inner
suburban departments. Mayotte would comprise only large housing estates, car parks, and
In such a context, controlling immigration is a prerequisite for stabilising the socio-
economic framework. The resources devoted to the fight against illegal immigration have been
strengthened and better organised since 2018.
Crime in Mayotte has reached an unprecedented level, and security has become the
primary concern of the inhabitants; confidence in the police is low.
In the field of education, the lag is difficult to offset. The level of school facilities in the
territory and the demographic growth make it necessary to build on a massive scale. Lost time
is being made up for in terms of secondary education. However, the construction rate of
primary schools is far too low in relation to the 850 additional classes needed to accommodate
children under satisfactory conditions. The education level of remains low, in an archipelago
where half the population does not speak French.
In the face of such challenges, public institutions do not have the necessary basis to lead
the archipelago’s development with clarity.
The local authorities, which are still in their first steps, starting with the department itself,
lack expertise and engineering. The emergence of a Mayotte elite still does not provide
sufficient number of the managers that Mayotte needs. More support will be needed, while
respecting the powers of local authorities. The department's project management capacity
remains insufficient, although it has undertaken to upgrade the skills of its managers. Its
financial situation is satisfactory, because of delays in the effective exercise of its powers and
in the implementation of its investment programmes.
Central government services are weakened by the fact that the number of staffs has
been drastically reduced, in ignorance of the difficulties that are not comparable to those
encountered in mainland France. The staff of the prefecture, in particular, are too busy handling
successive emergencies to provide the impetus and coordination necessary for the
development of the archipelago. In addition, their high turnover, the resulting vacancies, and
the insufficient formalisation of initiatives have led to a rapid loss of memory, which affects the
continuity of the actions undertaken.
Court of Accounts,
La départementalisation de Mayotte [Departmenthood of Mayotte]
, Public thematic report,
In recent years, the central government has implemented two action plans for Mayotte.
The first, named "Mayotte 2025", was announced in 2015. With 324 actions, this plan,
which had no specific allocated resources, established objectives that were often imprecise
and did not address the issues of security and immigration, which are central to the concerns
of the people of Mayotte. It did not receive monitoring and leadership beyond one year. No
assessment of the plan was established and there was no reporting beyond its first year of
implementation. Its contribution to the needs of the territory and the population of Mayotte were
The second, the "
plan pour l’avenir de Mayotte
(Plan for the Future of Mayotte)", was
drawn up as an emergency response to the social crisis in early 2018, which paralysed the
archipelago over two months. Consisting of 53 measures and at a reported cost of
it combined emergency measures and long-term proposals. It devoted an entire section to
immigration and security issues, which were at the root of the crisis. During the first year of its
implementation, the plan brought a new dynamic to the central government's action in Mayotte
and saw significant progress, with the creation of a regional health agency and a full-fledged
education authority, a renewed effort in the fight against illegal immigration, and more
resources devoted to security.
The major investment component of this second plan was formalized in the convergence
and transformation contract concluded in fall of 2019, as in other overseas territories. The
progress on such investments varies, depending on the capability of the project owners to
complete them. While secondary school construction continues at a satisfactory pace, there
has been little progress on primary schools and on water sanitation and public transport
networks. This plan, like the previous one, only received structured monitoring for a short
All in all, there is currently no strategic programming document for the development of
Mayotte. The preparation of the regional development plan, started in 2011, has still not been
completed. The Operation of National Interest provided for in the 2018 plan has so far only
given rise to an outline, which has not been supported by Mayotte elected officials.
Land disputes, a cause of uncertainty about property ownership that was highlighted
during the transition to formal law, are a major handicap to public action. There has been little
progress in settling them, despite the 2017 creation of the Mayotte Public Land and
Finally, the spread of informal and/or unhealthy housing could not be stopped. The share
of insecure housing, at around 40%, did not change from 1997 to 2017, and the increase in
annual social housing production in recent years is not at all in proportion to the need.
On each of these topics, project management is not coordinated enough. However, the
Court stressed this need when it published its 2016 report on Mayotte departmenthood.
Following extensive consultation with the people of Mayotte and their elected
representatives, the Government prepared a bill for the accelerated development of Mayotte2.
On 13 January 2022, the departmental council issued an unfavourable opinion on this bill and
it was abandoned.
An in-depth strategic reflection on the sustainable development of Mayotte has yet to be
conducted. Otherwise, the archipelago will remain dependent on Government funding from the
mainland, which seems neither desirable for the people of Mayotte nor sustainable in the long
term given the demographic outlook.
