The significant decline of fertility may be explained partly by the increase in modern contraceptive use as shown by the increase in Contraceptive Prevalence Rate (CPR) from 10% in 2005 to 45% in 2010, then to 48% in 2015 (2014-15 DHS), and then to 58% in 2020 (2019-20 DHS) [Figure 3.3].
Another contributory factor is the observed increase in net attendance rate in secondary school for girls that increased from 10% in 2005 to 21% in 2012 (EICV 2010-11), and then to 39% in 2020 (2019-20 DHS). More generally, the fertility decline resulted from the government policy of raising public awareness down to the village level for the adoption of responsible parenthood behaviours and ensuring availability of community health services at the lowest geographical level.

3.4.2. Mortality levels and trends Mortality is a key component of population change and has influence across all ages. The pattern of mortality by age usually assumes a near “U”-shape - suggesting high concentration of deaths in the very early and older ages. It is measured by a number of indicators including crude death rate (CDR), life expectancy at birth (LEB), infant mortality rate (IMR) and under-five mortality rate (U5MR). Life expectancy at birth is the best summary indicator to measure the level of mortality, health status and wellbeing of the population. As presented in Table 3.2, life expectancy at birth (e0) in Rwanda was 46.4 years in 1978, it increased to 53.7 years in 1991, before decreasing to 51.2 years in 2002. Thereafter, it has recorded increases: from 51.2 years to 64.5 years (about 26%) between 2002 and 2012; and from 64.5 years to 69.7 years (about 8%) between 2012 and 2022. The decline in mortality is further reflected in the substantial reduction in IMR: from 144 per 1000 live births in 1978 to about 49 in 2012, and then to 29 in 2022 (Figure 3.4). The under-five mortality has followed the same pattern of decline. The changes in IMR between 1992 and 2002 were trivial, which is explained by the influence of the 1994 genocide. Most of the decline in mortality actually took place during the last two decades.

The increase in life expectancy at birth (Figure 3.5) is due to the improvement of the health status of the population, especially during the last two decades following several vigorous social and health care interventions aimed at reducing the leading causes of death through: improved capacity (in both health personnel and infrastructures); improvement in the public hygiene systems and universal access to health insurance by the population.

Migration levels and trends The pattern of migration in Rwanda varies according to the type of migration, internal versus international. Regarding internal migration, majority of the population of Rwanda remains in their place of origin, since only 20% of the resident population were reported to reside in a district other than their district of birth (lifetime migrants), and 10% were reported having resided in a district different from their current district of residence (recent migrants) in the last five years preceding the census date. The percentage is even lower if one considers the change of residence at the province rather than the district level. The analysis of the origin and destination of migrants (migration flows) shows evidence that most migrants who changed their residence between provinces tend to move to neighbouring provinces. Conversely, provinces receive migrants from neighbouring provinces or countries. The City of Kigali and Eastern Province received more migrants than other provinces of the country, regardless of the type of migration considered. As for international migration, the stock is negligible as compared to the size of the whole population. Although there have been significant cross-border migration in Rwanda in the 1990s triggered by the 1994 genocide against Tutsi, this unusual phenomenon is unlikely to reoccur in the future. According to the 2022 PHC data, the foreigners represented only 1% of the resident population of Rwanda. This clearly implies that international migration has negligible impact on population change in Rwanda and, therefore, the assumption of negligible net international migration was retained for the projections at national level in the Rwandan context.

CHAPTER 4: PROJECTION PARAMETERS, ASSUMPTIONS AND SCENARIOS
Population
projections
are
based
on
how
assumptions of the different parameters are
specified. Given that population growth rate has
implications on all sectors of national life, population
projections should integrate a systematic analysis of
past trends of demographic components and derive
realistic assumptions of future trajectories. Rwanda,
with an average annual growth rate of 2.3%,
resembles other Sub-Saharan African countries
where rapid population growth constitutes a serious
threat on national development.
Indeed, at this rate of growth, the population of
Rwanda is expected to double in 30 years reaching
more than 26 millions by 2052. Given the relatively
small surface area of Rwanda (just above 26
thousands square kilometres), this rapid population
growth is expected to exert tremendous demographic
pressure
on
available
resources
especially
agricultural land in the future. The population density
would be around 1000 per square kilometer. The
population projections are generated over a period
of 30 years - from 2022 to 2052 in single and 5-year
age-groups.
4.1.
Projection parameters
The projection parameters considered here are the distribution of the resident population by sex, age and area of
residence, fertility and mortality and migration.
4.1.1.
Total, urban and rural population
The base population is the 2022 mid-year (1st July
2022) population from the RPHC5 data disaggregated
by sex, age and area of residence. It was obtained by
retro-projecting the resident population enumerated
by the RPHC5 that refers to 15th August 2022 using the
2012-2022 intercensal annual growth rate. Figure 4.1,
Figure 4.2, and Figure 4.3 present the distribution of
the base population by sex, age and area of residence
(Total, Urban and Rural).
It has to be noted that the national population sex
ratio of 94 males per 100 females is a reflection of the
deficit of men in rural areas (92 males per 100
females) whereas that in urban areas is (101 males
per 100 females). Further analysis shows that men in
the adult ages are more represented in urban areas
suggesting labour migration flows of men from rural
to urban areas. On the other hand, there is a balance
in sex ratio in the population aged 0-4 years (Table
4.1).

4.1.2.
Fertility
Fertility indicators considered for the population
projections are total fertility rate (TFR) and the age-
specific fertility rates (ASFRs).
a) Trends in total fertility rate The base value for the TFR is set at 3.6 children per woman derived from the RPHC5 thematic report on Fertility. The value of TFR has been dropping from 5.9 in 2002, to 4.0 in 2012. b) Age-specific fertility rates As for the age-specific fertility rates, the projections is expected to use the rates provided by the RPHC5. However, these are normalized so that the sum of the ASFRs are 100%. In other terms, what is used as input for the projections are the respective contributions of the 5-year age-groups to the total fertility as measured by the TFR, as shown in Table 4.2.
