About this dataset

Context

The dataset tabulates the Key West population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of Key West across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2023, the population of Key West was 25,103, a 1.81% decrease year-by-year from 2022. Previously, in 2022, Key West population was 25,566, a decline of 1.60% compared to a population of 25,981 in 2021. Over the last 20 plus years, between 2000 and 2023, population of Key West decreased by 322. In this period, the peak population was 26,360 in the year 2020. The numbers suggest that the population has already reached its peak and is showing a trend of decline. Source: U.S. Census Bureau Population Estimates Program (PEP).

About this dataset

Context

The dataset tabulates the data for the Key West, FL population pyramid, which represents the Key West population distribution across age and gender, using estimates from the U.S. Census Bureau American Community Survey (ACS) 2018-2022 5-Year Estimates. It lists the male and female population for each age group, along with the total population for those age groups. Higher numbers at the bottom of the table suggest population growth, whereas higher numbers at the top indicate declining birth rates. Furthermore, the dataset can be utilized to understand the youth dependency ratio, old-age dependency ratio, total dependency ratio, and potential support ratio.

Key observations

• Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Key West, FL, is 17.5.
• Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Key West, FL, is 29.4.
• Total dependency ratio for Key West, FL is 46.9.
• Potential support ratio, which is the number of youth (working age population) per elderly, for Key West, FL is 3.4.

Evaluating genetic diversity of seagrasses provides insight into reproductive mode and adaptation potential, and is therefore integral to broader conservation strategies for coastal ecosystems. In this study, we assessed genetic diversity, population structure and gene flow in an opportunistic seagrass, Syringodium filiforme, in the Florida Keys and subtropical Atlantic region. We used microsatellite markers to analyze 20 populations throughout the Florida Keys, South Florida, Bermuda and the Bahamas primarily to understand how genetic diversity of S. filiforme partitions across the Florida Keys archipelago. We found low allelic diversity within populations, detecting 35–106 alleles across all populations, and in some instances moderately high clonal diversity (R = 0.04–0.62). There was significant genetic differentiation between Atlantic and Gulf of Mexico (Gulf) populations (FST = 0.109 ± 0.027, p-value = 0.001) and evidence of population structure based on cluster assignment, dividing the region into two major genetic demes. We observed asymmetric patterns in gene flow, with a few instances in which there was higher than expected gene flow from Atlantic to Gulf populations. In South Florida, clustering into Gulf and Atlantic groups indicate dispersal in S. filiforme may be limited by historical or contemporary geographic and hydrologic barriers, though genetic admixture between populations suggests exchange may occur between narrow channels in the Florida Keys, or has occurred through other mechanisms in recent evolutionary history, maintaining regional connectivity. The variable genotypic diversity, low genetic diversity and evidence of population structure observed in populations of S. filiforme resemble the population genetics expected for a colonizer species.

Caribbean acroporid species have undergone extreme declines in abundance since the 1980s. Population-level recovery will depend on re-colonization by juveniles (fragments or sexual recruits), which are particularly vulnerable to threats such as predation and disease. Demographic monitoring of juvenile Acropora cervicornis and A. palmata colonies was undertaken in the Florida Keys (USA) to determine the fate of various initial colony conditions as expressed by growth and survivorship over an 18 month study. Both healthy colonies and those with signs of recent predation or disease were selected at several sites, measured, photographed and reassessed periodically between summer 2002 and winter 2003-04. Most A. palmata colonies (72%) that were initially healthy were still healthy at the study's conclusion. Snail (Coralliophila abbreviata) predation resulted in partial mortality which decreased growth for A. palmata. Snail-infested colonies tended to retain snails for several months to a year. White-band disease affected several colonies throughout the survey but did not result in complete mortality of any tagged colonies. Only half of the initially healthy A. cervicornis colonies remained healthy, while 38% lost substantial tissue or died of a rapidly progressing disease of unknown etiology. Predation by the fireworm Hermodice carunculata was extremely common. Although it was associated with relatively little live tissue loss, it is postulated to have profound effects on growth since it feeds selectively on the growing tips. Regardless of initial condition, A. cervicornis lost substantial tissue more often than A. palmata suggesting that A. cervicornis may be even more imperiled than its congener.

In 1998, the Florida Fish and Wildlife Conservation Commission's (FWC) Fisheries Independent Monitoring (FIM) program began a long-term monitoring effort of key reef fish populations in the Florida Keys National Marine Sanctuary. This effort was aimed at evaluating the relative abundance, size structure, and habitat utilization of specific reef fish species that are targeted by commercial and recreational fisheries.

This record refers to ongoing population surveys of corallivorous snail, C. abbreviata, and two of its coral hosts, Acropora palmata, and Montastraea spp at six reef sites (three open and three in no-take zones) in the upper Florida Keys National Marine Sanctuary. Surveys are conducted annually in Apr-May. A set number of colonies of each host is searched for snails. Each colony is measured and...

About this dataset

Context

The dataset tabulates the population of Key West by gender across 18 age groups. It lists the male and female population in each age group along with the gender ratio for Key West. The dataset can be utilized to understand the population distribution of Key West by gender and age. For example, using this dataset, we can identify the largest age group for both Men and Women in Key West. Additionally, it can be used to see how the gender ratio changes from birth to senior most age group and male to female ratio across each age group for Key West.

Scope of gender :

Please note that American Community Survey asks a question about the respondents current sex, but not about gender, sexual orientation, or sex at birth. The question is intended to capture data for biological sex, not gender. Respondents are supposed to respond with the answer as either of Male or Female. Our research and this dataset mirrors the data reported as Male and Female for gender distribution analysis.

In terms of the share of its total population, the Lower Florida Keys are most at risk to homes being flooded by rising sea levels, with ** percent of its residents living in dwellings expected to be flooded by 2060. Although Chesapeake, Virginia has a relatively small percentage of its population at risk, the number of inhabitants living in homes expected to be flooded is very large.
