A Multidimensional Statistical Analysis of Artisans and Unskilled Workers of Ecuador

The objective of this study is to highlight the social characteristics of the unskilled workers and artisans of Ecuador through a descriptive and multidimensional statistical analysis of data from the 2015 National Survey of Employment, Unemployment and Self-employment. The descriptive statistical analysis demonstrates the frequencies and percentages of the variables of the investigation while the multidimensional statistical analysis shows the principal criteria of differentiation and classification between the groups of people surveyed. The methods involved a factorial analysis of multiple correspondences indicating the criteria of differentiation, and a statistical hierarchical analysis, which attempts to define the subjects surveyed according to their common traits.


Introduction
Unskilled workers or laborers and artisans constitute 12.57% of the economically active population in Ecuador, according to the 2015 National Survey of Employment, Unemployment and Self-employment.The term "unskilled worker" in the Ecuadorian context refers to uneducated workers who either operate heavy machinery or engage in manual labor, whereas, the term "artisan", is used to refer to a person who is skilled at making objects (decorative or functional) by hand.Additionally, the labor of the artisan or crafts person, unlike that of the unskilled worker in Ecuador, is legally recognized due to the fact that Ecuadorian artisans are protected by law (the Legislation of Artisans Act) and are certified by the National Defense of Craftsmen.In fact, Ecuadorian artisans enjoy certain privileges, such as tax incentives, which distinguish them from unskilled workers and serve to strengthen their sector.Despite this, however, unskilled workers and artisans are closely related in the types of activity they undertake, and by the fact that an unskilled worker could change his status to qualified artisan by becoming affiliated with the National Defense of Craftsmen.It is for this reason, and the fact that these two groups of workers make up 12.57% of the working population in Ecuador, that we have chosen to do a multidimensional statistical analysis on these two sectors.Hence, this study proposes to give us a general outlook on the social characteristics of both unskilled workers and artisans, in an effort to contribute to the formulation of strategies and policies that could improve their living conditions.

Methodology
As mentioned before, the development of this study was based on data from the 2015 National Survey of Employment, Unemployment and Self-employment (ENEMDU), which was downloaded from the official website of the National Institute of Statistics and Census (INEC, 2015).This information was analyzed using the statistical software R, which allowed us to distinguish the most relevant variables of the data provided and work with this information in relation to the statistical necessities of the study.Subsequently, the factorial analysis was performed using SPAD software which allowed for the formulation of seven groups based on their distinctive characteristics.
The study consists of a descriptive as well as a multidimensional statistical analysis.The descriptive analysis demonstrates the frequencies and percentages of the variables under study (Athanasiadis, 1995) and the multidimensional statistical analysis shows the principles and the most important criteria of differentiation and classification between the groups of the people surveyed.The methods used were a factorial analysis of multiple correspondences which illustrates the criteria of differentiation, and a hierarchical analysis, which defines the groups of people surveyed according to their common characteristics (Stefos et al., 2011), the information of which can also be represented in a classification table connecting these clusters (Papapostolou et al., 2013).On the other hand, the factorial analysis of multiple correspondences shows the diversity of the sample population with relation to the answers given in the surveys, while determining the correlation between the variables of the survey.The SPAD v.4.5 Software was used for the data analysis provided by the Faculty of Humanities of the University of the Aegean.The population of unskilled workers and artisans living in the urban and rural areas is 78.36% and 21.64%, respectively (Table 1).An overwhelming majority of the population surveyed are male (81.45%) while only 18.55% are female (Table 2).The age group of 15 to 24 year olds represents 12.93% of the population while the largest percentage of the sample population is represented by the age group of 25 to 34 year olds (26.55%), followed by the population of 35 to 44 year olds (24.68%), 45 to 54 year olds (19.51%), 55 to 64 year olds (11.69%), 65 to 74 year olds (3.95%), 75 to 84 year olds (0.67%) and lastly, 85 to 94 year olds (0.03%) (Table 3).The percentage of the population without any level of education is as low as 1.56%, with only 0.27% declaring that that they attend a literacy center.The subjects surveyed with only a primary school level of instruction, however, constitute as much as 38.17% of the population, with slightly a higher percentage (42.75%),almost half of the population, representing those who have only gone up to high school.Comparatively speaking, nevertheless, only 6.25% of the subjects said that they only have a secondary school education while as little as 2.45%, declared that they only have a basic education level of instruction.Conversely, less than ten percent of the population (7.49%) are shown to have advanced university studies and even less, postgraduate studies (0.06%) (Table 5).Spanish is the language spoken by the majority of Ecuadorians (94.97%), although the majority of the rest of the population surveyed speak both Spanish and an indigenous language (4.43%).A very small percentage, however, can speak both Spanish and a foreign language (0.50%), although this percentage is higher than that of those who only speak an indigenous language (0.04%) or both an indigenous and a foreign language (0.03%).Even the percentage of Ecuadorian subjects who do not speak (0.09%) is higher than that of Ecuadorians who only speak an indigenous language and who speak both an indigenous and a foreign language put together (0.07 %) (Table 6).According to the data collected, 85.10% of the population in the study consider themselves to be mestizo, 5.88% to be indigenous, 2.96% to be Montubio, 1.64% to be black, 1.56% to be white, 1.51% to be Afro-Ecuadorian, 1.29%, mulatto, and 0.06%, other (Table 7).The statistical data show that 19.39% of the sample population have either a permanent, indefinite or stable contract, while 17.14% have a labor contract for either temporary, occasional or sporadic work.Additionally, 14.88% of the subjects surveyed are contracted for day labor while less than a third of that percentage are hired for piecework 3.28%.Only a small percentage of the subjects under study are hired by assignment 1.02% or by the hour (0.59%) (Table 8).An overwhelming majority of the sample population (70.56%) claim to feel content at work while roughly 16.52% describe themselves as "somewhat content", which means that almost 90% of the subjects surveyed are relatively content in their jobs.Comparatively speaking, however, only 10.03% of the population studied are unsatisfied but conformant with their jobs with just under a third of this percentage 2.70% claiming to be totally discontent with their line of work and 0.19% either do not know or are unresponsive (Table 9).A large majority of the sample population 80.16% have an activated cellular phone compared to 16.04% of the population who claim not to own one (Table 10).On the other hand, the percentage of the subjects who own a smart phone is approximately 6% more than those who own an activated cellular phone, almost a quarter of the population 22.09%.Nevertheless, a little over half of the population sampled do not own a smart phone 58.07%(Table 11).Similarly, more than half of the population have not used the Internet in the past 12 months 55.72%, although as much as 40.49% of the population have (Table 13).In relation to the region of origin, 49.04% of the unskilled laborers and artisans surveyed have declared themselves to be from the mountain region of Ecuador, followed closely by a percentage of 47.83 who claim to be from the coastal region.The Amazon Region, 3.02% and the Islands 0.11% represent a very small percentage of these two sectors (Table 14).It was determined that the majority of the subjects surveyed, approximately half 44.43%, work in manufacturing industries, followed closely by 32.24% who work in construction.Another significant branch of activity for unskilled workers and artisans would seem to be commerce and vehicle repair as it is constituted by 11.42% of both these groups.Conversely, nearly half of this percentage 5.96%, however, represents those who claim to be engaged in other unspecified activities and services, while roughly a third of that percentage (1.80%),are involved in cattle raising, hunting, forestry and fishing.Other activities, however, such electricity, gas and air conditioning supply (0.65%), information and communication (0.72%), defense and social security (0.85%), draw just under one percent of the population while a very minimal percentage of the subjects surveyed are dedicated to activities such as teaching (0.05%) and arts, entertainment and recreation (0.02%) (Table 15).According to the data, 84.40% of the population are not considered to be poor, while 14.52% are (Table 16).According to the statistical data, 94.88% of population are not considered to be indigent, while 4.03% are (Table 17).Based on the statistical data below, a little over half of the sample population, approximately 52.47%, are classifiable as having adequate employment, yet more than a quarter of the population (27.92%), however, are considered to have inadequate employment.Interestingly, the third largest percentage in this variable (12.62%) represents the subjects who are underemployed due to insufficient work time, although those unskilled workers or artisans who are underemployed due to insufficient income is considerably less (4.79%).Conversely, the percentages of the population surveyed who engaged in unpaid employment (1.76%) or unclassified employment (0.44%) were significantly smaller (Table 18).

Factorial Analysis of Multiple Correspondences
The method of factorial analysis of multiple correspondences was used to categorize the sample population according to the answers they provided.As a result, the criteria of differentiation are: First criterion of differentiation (inertia percentage 8.28%) According to the information gathered from the first axis, there is a relatively small percentage of the population who have used a computer and the Internet over the past 12 months, have a smart phone, are not poor and are between the ages of 15 and 24.On the other hand, there are those who do not own cellular phones, have not used a computer or the Internet in the past 12 months, whose level of instruction only goes up to primary school, and who are employed as manual laborers.
Second criterion of differentiation (inertia percentage 7.45%) Regarding the second axis, this percentage represents that sector of the population who own cellular phones but have not, however, used a computer or the Internet in the past 12 months, who are regarded as poor and who only have a primary school level of education.These are differentiated from the portion of the population who are single, between the ages of 15 and 24, are not poor and have either a temporary, occasional or eventual work contract.
Third criterion of differentiation (inertia percentage 5.53%) The third focal point, represents women who work in manufacturing industries, live in an urban area (primarily in the coastal region), speak only Spanish and regard themselves as mestizos.On the other hand, this criterion also serves to distinguish these subjects from the men who either do manual labor or work in construction, are satisfied with their jobs, regard themselves as indigenous and live in the rural regions.

The Hierarchical Analysis
The hierarchical analysis consists of seven groups as shown in the chart below.The people from the first group have declared that they have had access to a computer and the Internet over the past 12 months.They own a smart phone, have a high school education but do not attend university.Additionally, this cluster represents those who are not considered to be poor, regard themselves as mestizos, live in the urban areas and are mostly between the ages of 25 and 34.
Second cluster, 9.32% of the sample The subjects of the second group are younger than those of the first cluster with ages ranging from 15 to 24 years old.They have a basic or high school education and have used a computer and the Internet in the past 12 months.They are single and the majority of them work in commerce and vehicle repair with either temporary, occasional or eventual work contracts.
Third cluster, 7.81% of the sample The people from this group identify themselves as indigenous, speak an indigenous language in addition to Spanish, live in urban areas, either work in construction or do manual labor, have used a computer and the Internet in the past 12 months but are regarded as poor.Conversely, most of the subjects of this sector have a primary school education and are married.
Fourth cluster, 7.56% of the sample The surveyed subjects of the fourth cluster are considered to be poor and indigent, and are either self-employed or hold an unsuitable job.Most of them are between 35 and 44 years of age, have not used a computer nor have they accessed the Internet in the past 12 months.They do not own smart phones and few are pleased with their jobs.
Fifth cluster, 31.88% of the sample The fifth group is constituted by people who answered that they have not used a computer or the Internet in the past 12 months.However, although they do not own smart phones, they have cellular phones and are over 45 years old.These subjects, who regard themselves as mestizos, are not considered to be poor and generally speaking, tend to work in construction.
Sixth cluster, 13.22% of the sample The subjects of the sixth cluster are older than 65, only speak Spanish, have only got a basic level of education, do not own a cellular phone and have not used a computer or the Internet in the past 12 months.
Seventh cluster, 2.38% of the sample The people from the seventh group are men who live on the coast or in the Amazon region.They do not have cellular phones and work in either manufacturing or electricity, gas and air conditioning supply.
Figure 2. Correspondence analysis These differences among groups are shown in Figure 2 where the Graph of Correspondence Analysis (factorial level 1x2) presents the centroids from the seven groups in two axes.It also defines the differences and similarities between the subjects surveyed of the seven groups (Olivier, 2008).

Conclusion
The objective of the present study was to investigate the social characteristics of the unskilled workers and artisans of Ecuador.The results of the multidimensional statistical analysis, hence, illustrate the following: most of the trade workers and artisans in Ecuador live in urban areas 78.36%, the majority are men 81.(Stefos, 2015).
