The Monthly Indicator of Industrial Activity is expressed as a quantity index of Laspeyres formulation, which is based in the year 2003, which reflects the actual volume of gross value added at basic prices obtained in the month. The conceptual framework and methodology used is similar to that used in the Goods and Services Accounts System of National Accounts of Mexico (SCNM).
Indices are calculated for 321 physical volume of 374 kinds of economic activity Industrial Classification System North American (NAICS) covering the year 2002. These classes integrate 29 sub-sectors of economic activity included in this indicator, grouped in four sectors: Mining, electricity, water and gas supply pipeline to the final consumer, construction, and manufacturing.
Mining: Includes economic units principally engaged in oil and gas, and metallic and nonmetallic minerals, including quarrying, well operations, operations profit and other preparations are usually done at the mine. It also includes unique support services to mining. To calculate the indicator uses data from the Mining and Metallurgy Industry Statistics and the Monthly Industrial Survey prepared by the INEGI, the company Exportadora de Sal, SA de CV and Petróleos Mexicanos (PEMEX).
Electricity, Water and Gas supply through pipelines to final consumers: Includes services of generation, transmission and supply of electricity for sale, to the collection, purification and water supply as well as collection and treatment of wastewater, and the supply of gas through pipelines to final consumers, the main sources are the Federal Electricity Commission, Commission Regulatory Energy (CRE) and PEMEX.
Construction: Includes residential construction activities, whether single family or multifamily housing, a non-residential construction, such as ships and industrial plants, commercial buildings, and institutional services, the construction of civil engineering works such as bridges, roads, dams, railways, power plants and ports to the completion of specialized work, such as foundations, erection of prefabricated structures, installation of equipment and buildings prefabricated materials, finishes in buildings, demolition, land filling, earthwork, excavation, drainage and other preparations to the soil. It may be new construction, expansion, remodeling, maintenance or repair of buildings integral. It also includes construction operations; to the supervision and administration of construction projects and construction works in combination with service activities.
Thus, the indicator is weighted based on the behavior of apparent consumption (production and / or domestic over imported goods exported minus) of the main materials used by 236 sub Building, 237 Building and civil engineering works or heavy work and 238 workers for the construction derived from NAICS. Calculations were also used data from the Balance of Trade, sales or domestic production provided by chambers, associations and monthly surveys, such as the mining-metallurgical, manufacturing and related to the construction.
Manufacturing Industries: It covers the activities involved in processing mechanical, physical or chemical materials or substances in order to obtain new products. Also considered maquila manufacturing activities, the assembly of parts and components or products manufactured rebuilding machinery and industrial equipment, commercial, office and others, and finishing of manufactured products by dyeing, heat treatment, plating and processes similar. Also this includes the mixture of materials such as lubricating oils, plastic resins, paints and spirits, among others. The work of transformation can be performed in places such as plants, factories, workshops, maquiladora or households, whether the work is performed using power-driven machines or equipment manual.
The main source of information is the Monthly Industrial Survey is complemented by data from chambers and associations of producers and public and private institutions, such as PEMEX, Banco de Mexico (BANXICO), Mexican Association of Automotive Industry, CA and National Association Producers of Buses, Trucks and Tractors, AC, among others.
Importantly, the vast majority of economic series are affected by seasonal factors. These are periodic effects that are repeated every year and whose causes can be considered outside the economic nature of the series, such as holidays, the fact that some months are more days than others, the school vacation periods, the effect of climate in different seasons, and other seasonal fluctuations, for example, the high production of toys in the months leading up to Christmas caused by expectations of higher sales in December.
In this sense, the seasonal or seasonal adjustment of economic series is to remove these influences intra-annual periodical, because its presence difficult to diagnose or describe the behavior of economic series, unable to properly compare a given month with the immediate past.
Analyze the seasonally adjusted series helps make a better diagnosis and prognosis of the evolution of it, as it facilitates the identification of the likely direction of movements that could have the variable in question, in the short term. It is noted that the seasonally adjusted series of the total industrial production is calculated independently of its four components.
