Demographics:

Trends that describe the historical changes in the population over time (for example, the average age of a population may increase or decrease over time). Both distributions and trends of values within a demographic variable are of interest.

Demographic transition:
Is the process by which countries pass from a situation of high birth and death rate to one of low rates. More education and higher living standards reduce the birth rate and increase the age of life expectancy. As a result, the average age and affluence of the population increases and this affects the type of purchasing decisions made in the economy.

Density:
Also known as “specific gravity”. In physics, the lightness or heaviness of different substances is denoted by using the word density. The density of a substance is defined as the mass of the substance per unit volume. The density of water varies due to parameters such as temperature and salt content. Impurities also play a significant role in changing the density of water. The instrument to measure the density of a liquid is called a hydrometer.

Direct employment:

Good:
A commodity, or a physical, tangible item that satisfies some human want or need, or something that people find useful or desirable and make an effort to acquire. Goods that are scarce (are in limited supply in relation to demand) are called economic goods, whereas those whose supply is unlimited and that require neither payment nor effort to acquire (such as air) are called free goods.

Grain:
A grain is a small, hard, dry seed (with or without hull or fruit layers attached) harvested for human food or animal feed. The plants producing such seeds are called ‘grains’ or ‘grain crops’

Grain elevator/vertical silo:
A structure for storing bulk materials. Silos are used in agriculture to store grain or fermented feed known as silage. Silos are more commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. Three types of silos are in widespread use today – tower silos, bunker silos and bag silos.

Hopper car:
A type of railroad freight car used to transport loose bulk commodities such as coal, ore, grain and track ballast. Two main types of hopper car exist: covered hopper cars, which are equipped with a roof, and open hopper cars, which do not have a roof.

Hump yard:
A classification yard found at some freight train stations, used to separate railroad cars on to one of several tracks. First the cars are taken to a track, sometimes called a lead or a drill. From there the cars are sent through a series of switches, called a ladder, onto the classification tracks. Larger yards tend to put the lead on an artificially built hill called a hump to use the force of gravity to propel the cars through the ladder. The classic hump yard is simply a method of using gravity to sort and switch cars in a rail yard. Cars get pushed up the “hill” and are released at the top. At the bottom of the other side of the hill is a series of tracks with power switches that a Yard Master operates from a tower above the hill. As the cars roll down the hill, the yardmaster operates the switches so that each car glides into the track that he or she wants it to go into. The cars will usually travel at a speed that allows them to couple with other cars in the track. This is one method that a railway uses to sort cars into different destinations.

Import:
A product that is shipped into a country or region.

Inclined plane:
A plane set at an angle to the horizontal; a simple machine used to raise or lower a load by rolling or sliding.

Indirect employment:

Induced employment:
The employment multiplier effects (number of jobs) caused by successive rounds of spending through the economy as a result of the port’s direct and indirect effects. For example, employees use their salaries and wages to purchase goods and services from other businesses. Businesses make their own purchases and hire employees who in turn make their own purchases. In the input-output method, the port’s total economic impact is the sum of the direct, indirect and induced effects.

Insurance agent/broker:
An individual who sells, solicits, or negotiates insurance for compensation.

International trade:
The exchange of goods or services along international borders. This type of trade allows for a greater competition and more competitive pricing in the market.

Machinist:
A worker who fabricates, assembles, or repairs machinery.

Marine pilot:
Is the experienced and professional licensed mariner whose role is to advise the Captain of a ship on the safest route to be taken to bring a vessel into its port of call. Although Captains are familiar with their own vessel and crew, they are not necessarily familiar with every port their vessels visit and so they require the local expertise of a Marine Pilot to ensure that their ship, its crew, passengers and cargo arrive at their port of call in a safe and efficient manner. Marine Pilots are intimately familiar with the coastlines, inland waters, shoals, harbours, ports, weather, tides, shipping regulations and restrictions of the area for which they are licensed and use their experience to prevent vessels from grounding on shoals or colliding with other vessels. Marine Pilots are also familiar with the different propulsion systems, hull designs, and rudder characteristics of various types of ships and how these will react at different speeds and in different wind, tidal and current conditions.

Marine engineer:
Is responsible for all heavy machinery on a ship or an offshore structure at a marine terminal.

Marine surveyor:
A person who inspects or examines marine vessels to assess and make reports on their condition. This is done to make sure that they meet certain standards or specifications. Marine surveyors usually work in the shipping logistics and repair, marine and engineering consultancy, and public safety industries.

Marine terminal:
That part of a port or harbour with facilities for docking, cargo handling, and storage.

Mass:
In physics, the quantity of matter in a body regardless of its volume or of any forces acting on it. The term should not be confused with weight, which is the measure of the force of gravity acting on a body. Under ordinary conditions the mass of a body can be considered to be constant; its weight, however, is not constant, since the force of gravity varies from place to place. There are two ways of referring to mass, depending on the law of physics defining it: gravitational mass and inertial mass. The gravitational mass of a body may be determined by comparing the body on a beam balance with a set of standard masses; in this way the gravitational factor is eliminated. The inertial mass of a body is a measure of the body’s resistance to acceleration by some external force.

Mechanic:
A worker skilled in making, using, or repairing machines, vehicles, and tools.

Oil spill:
The release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity. The term is usually applied to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land.

Plimsoll Line:
Is the line where the hull of a ship meets the surface of the water, in concept or reality. Specifically, it is also the name of a special marking, also known as the International Load Line or water line (positioned amidships), that indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise. Temperature affects the level because warm water provides less buoyancy, being less dense than cold water. Similarly, salinity affects the level because fresh water is less dense than salty seawater. The purpose of a load line is to ensure that a ship has sufficient freeboard (the height from the water line to the main deck) and thus sufficient reserve buoyancy

The post–World War II economic expansion, also known as the postwar economic boom, the long boom, and the Golden Age of Capitalism, was a period of economic prosperity in the mid-20th century, that occurred mainly in western countries following the end of World War II in 1945, and that lasted until the early 1970s. It ended with the collapse of the Bretton Woods system in 1971, the 1973 oil crisis, and the 1973–1974 stock market crash, which led to the 1970s recession. Narrowly defined, the period spanned from 1945 to 1952, with overall growth lasting well until 1971. During this time there was high worldwide economic growth; Western European and East Asian countries in particular experienced unusually high and sustained growth, together with full employment.

Pollution prevention:
