This statistic shows the usage of eggs in the United States in 2020. The data has been calculated by Statista based on the U.S. Census data and Simmons National Consumer Survey (NHCS). According to this statistic, 315.91 million Americans used eggs in 2020.

The demand of eggs has grown in the United States over the last number of years. In 2023, consumption of eggs in the United States was estimated at 281.3 per person. This figure was projected to reach 284.4 eggs per capita by 2024. Per capita consumption is a measure of total egg production, minus exports, divided by the total U.S. population.

Cage-free and organic eggs Although the majority of laying hens in the Unites States are still caged, the production of organic and caged-free hens has increased in recent years. In cage-free production, hens are allowed to move freely outside of their cage, but this time is limited and the environment they are kept in could still be unhealthy and very crowded. In organic production however, hens are provided with free-range outdoor access.

U.S. egg industry There has been steady growth in the number of eggs produced in the United States. Additionally, the total number of laying hens in the United States has also increased in recent years. Iowa was the U.S. state with the most laying hens, with some 40.16 million laying hens as of 2022.

This statistic shows the amount of eggs used within one month in the United States in 2020. The data has been calculated by Statista based on the U.S. Census data and Simmons National Consumer Survey (NHCS). According to this statistic, 57.55 million Americans used 5 dozen or more in 2020.

This statistic shows the amount of eggs used within 30 days in the United States from 2011 to 2020. The data has been calculated by Statista based on the U.S. Census data and Simmons National Consumer Survey (NHCS). According to this statistic, 57.55 million Americans used 5 or more dozens of eggs in 2020.

This statistic shows the total egg production in the United States from 2000 to 2023. In 2023, about 109.5 billion eggs were produced in the United States, a decrease from the previous year.

During 2010-2014, tree swallow (Tachycineta bicolor) reproductive success was monitored at 68 sites across all 5 Great Lakes, including 58 sites located within Great Lakes Areas of concern (AOCs) and 10 non-AOCs. Sample eggs were collected from tree swallow clutches and analyzed for contaminants including polychlorinated biphenyls (PCBs), dioxin and furans, polybrominated diphenyl ethers, and 34 other organic compounds. Contaminant data were available for 360 of the 1249 clutches monitored. Markov chain multistate modeling was used to assess the importance of 5 ecological and 11 of the dominant contaminants in explaining the pattern of egg and nestling failure rates. Four of 5 ecological variables (female Age, Date within season, Year, and Site) were important explanatory variables. Of the 11 contaminants, only total dioxin and furan toxic equivalents (TEQs) explained a significant amount of the egg failure probabilities. Neither total PCBs nor PCB TEQs explained the variation in egg failure rates. In a separate analysis, polycyclic aromatic hydrocarbon exposure in nestling diet was significantly correlated with the daily probability of egg failure. The eight sites within AOCs which had poorer reproduction when compared to 9 non-AOC sites, the measure of impaired reproduction as define by the Great Lakes Restoration Initiative, were associated with exposure to dioxins and furans, PAHs, or depredation. Only 2 sites had poorer reproduction than the poorest performing non-AOC. Using a classic (non-modeling) approach to estimating reproductive success, 82% of nests hatched at least 1 egg, and 75% of eggs hatched.

The Fluvial Egg Drift Simulator (FluEgg) estimates bighead, silver, and grass carp egg and larval drift in rivers using species-specific egg developmental data combined with user-supplied hydraulic inputs (Garcia and others, 2013, Domanski, 2020). This data release contains results from 240 FluEgg 4.1.0 simulations of bighead carp eggs in the Illinois River under steady flow conditions. The data release also contains the hydraulic inputs used in the FluEgg simulations and a KML file of the centerline that represents the model domain. FluEgg simulations were run for all combinations of four spawning locations, six water temperatures, and ten steady flow conditions. Each simulation included 5,000 bighead carp eggs, which develop and eventually hatch into larvae. The simulations end when the larvae reach the gas bladder inflation stage. The four spawning locations were just downstream of the lock and dam structures at Marseilles, Starved Rock, Peoria, and LaGrange. For each of these spawning locations, the eggs were assumed to have been spawned at the water surface and at the midpoint of the channel. The six water temperatures were 18, 20, 22, 24, 26, and 28 degrees Celsius. The ten steady flow conditions ranged from half the annual mean flow to the 500-year peak flow and are discussed in more detail below. Note that in the streamwise coordinate system used by FluEgg, the streamwise coordinate of the Mississippi River confluence is 396,639 meters. Any drift distances greater than this value should be excluded from any further analysis of this data. The hydraulic inputs for the FluEgg simulations were generated using a one-dimensional steady Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.7 model for the Illinois River between Marseilles Lock and Dam and the Mississippi River confluence near Grafton, Illinois (HEC-RAS, 2019). The HEC-RAS model was developed by combining four individual HEC-RAS models obtained from the U.S. Army Corps of Engineers Rock Island District (U.S. Army Corps of Engineers Rock Island District, 2003). The model was run for the following ten flow profiles: half the annual mean flow, annual mean flow, annual mean flood, 2-year peak flow, 5-year peak flow, 10-year peak flow, 25-year peak flow, 50-year peak flow, 100-year peak flow, and 500-year peak flow. The flow rates for each of the profiles were obtained for the following U.S. Geological survey (USGS) streamgaging stations from USGS StreamStats: 5543500 Illinois River at Marseilles, Illinois, 5558300 Illinois River at Henry, Illinois, 5560000 Illinois River at Peoria, Illinois, 5568500 Illinois River at Kingston Mines, Illinois, 5570500 Illinois River near Havana, Illinois, 5585500 Illinois River at Meredosia, Illinois, 5586100 Illinois River at Valley City, Illinois (Soong and others, 2004; Granato and others, 2017).

Pheno Forecast maps predict key life cycle stages in a range of species to improve conservation and management outcomes. For insect pest species, Pheno Forecasts are based on growing degree day (GDD) thresholds for key points in species life cycles. These key points typically represent life cycle stages when management actions are most effective. Emerald ash borer is a beetle that causes significant harm to ash trees throughout the eastern United States.The adult emergence and egg hatch forecasts for emerald ash borer was developed by Oregon State University, using the Degree-Days, Risk, and Phenological event mapping (DDRP) platform. The adult emergence model predicts the earliest date that overwintering individuals are predicted to emerge as adults. This event is predicted at 391 growing degree days (F) (lower threshold: 54F, upper threshold: 97F, method: single sine, start date: Jan 1). The egg hatch model predicts the earliest date that overwintering eggs are predicted to hatch. This event is predicted at 830 growing degree days (F) (lower threshold: 54F, upper threshold: 97F, method: single sine, start date: Jan 1). The forecast is available for the full calendar year. Temperature inputs are drawn from 3 data sources, as follows: PRISM data are used from Jan 1 through the current day; North American Multi-Model Ensemble (NMME) data are used from the current day through 7 months in the future and the most recent PRISM 10 year normal data are used for dates more than 7 months in the future. The model excludes climatically unsuitable locations for EAB using the current year's temperature data described above. Further information is available at USPest.org/CAPS. Forecasts are available for the current and prior year in the USA-NPN Visualization Tool (https://www.usanpn.org/data/visualizations).
