Population dynamics are governed by four demographic rates: births, deaths, immigration, and emigration. Variation in these rates and processes underlying such variation can be used to prioritize habitat conservation and restoration as well as to parameterize models that predict habitat-speciﬁc effects on population dynamics. The current understanding of patterns of habitat-speciﬁc demographic variability in exploited marine species, as well as processes underlying these patterns, was reviewed.We describe patterns of (i) habitat-speciﬁc density, followed by ontogenetic changes in habitat use, such as (ii) immigration (i.e. use as a settlement habitat) and (iii) emigration (i.e. use as a habitat for secondary dispersal to and from), and demographic rates such as (iv) growth, and (v) mortality. Despite the importance of coastal habitats for ﬁsh and invertebrate species and the vulnerability of these habitats to human impacts, therewas ambiguous evidence on their role in driving of population dynamics. Roughly 63% of the studies were descriptive, 21% experimental, and 11% used a combination of descriptive and experimental approaches, whereas 5%usedmeta-analyses.Habitat-speciﬁc densitywas themost common pattern quantiﬁed, followed by growth and mortality, with relatively few examples of studies of habitat-speciﬁc larval settlement. There were many examples of the inﬂuence of coastal habitats on survival, growth, and movement, especially at young stages, and there was an emerging focus on the effects of habitat degradation on demographic rates. There needs to be an increased effort on quantifying habitat-speciﬁc demographic rates and integrating these to better predict the effects of coastal habitats on the dynamics of exploited marine populations.
