The lithosphere is the upper layer of the earth, including the earth’s crust and upper mantle

The complete expulsion or extraction from its mother of a product of conception, irrespective of the duration of pregnancy, which, after such separation, breathes or shows any other evidence of life, such as beating of the heart, pulsation of the umbilical cord or definite movement of voluntary muscles, whether or not the umbilical cord has been cut or the placenta is attached; each product of such a birth is considered live born
(all live-born infants should be registered and counted as such, irrespective of gestational age or whether alive or dead at the time of registration, and if they die at any time following birth, they should also be registered and counted as deaths).

The total weight of undersized, unsalable or otherwise undesirable whole fish discarded live at the time of capture or shortly afterwards.

The total weight of fish that encounter the fishing gear, but avoid or escape it and remain alive.

An important role of the SBR is to maintain and to keep track of changes in statistical units and their characteristics that occur in the economy. Maintenance is a continuous process in which constant modifications of the set of statistical units occur over time. The extent of the modifications depends on the update strategy of the SBR. In this respect the SBR is considered to be a live register in which the composition and characteristics of units constantly change over time.The live register is a vehicle for bringing together data from the various sources that provide the basis for derivation of statistical units. It is the starting point for communications with the owners of the sources and for discussions about units. Legal units are usually the building blocks for creating statistical units. In some countries the SBR is the only environment in which legal units of all forms are brought together. Statistical units are created in the live register.

All animals, birds and insects kept or reared in captivity mainly for agricultural purposes.

Enumeration of livestock holdings undertaken in some countries separately from the agricultural census.

It encompasses all the cases in which livestock contributes “more than 10 percent to total farm output in value terms or where intermediate contributions such as animal traction or manure represent more than 10 percent of the total value of purchased inputs”.; A subset of a farm system.

Livestock for breeding, dairy, draught, etc consist of livestock that are cultivated for the products they provide year after year.

The livestock system refers to the general characteristics and practices of raising livestock on the holding.

To allow a comparison between different livestock herds, experts today employ the Tropical Livestock Unit (TLU), for which a TLU of one is equivalent to a 250 kg animal. A camel, for example, would give 1.0 TLU, while a sheep or goat would be equivalent to a TLU of 0.1. According to a study undertaken by the UK Department for International Development (DFID) in Ethiopia last year, for pure pastoralists to ensure minimum food security, a TLU of per capita of 3.0 must be maintained, guaranteeing sufficient stock for consumption and sales. To be economically independent, therefore, a pastoralist family of five would need a herd of at least 150 sheep and goats.

Infants born alive and are sill living regardless of age.

Are structurally separate and independent places of abode. They may: (a) Have been constructed, built, converted or arranged for human habitation, provided that they are not at the time of the census used wholly for other purposes and that, in the case of non-conventional housing units and collective living quarters, they are occupied at the time of the census; or (b) Although not intended for habitation, actually be in use for such a purpose at the time of the census.

A wage sufficiently high to permit a worker to keep a given standard of living.
