agricultural products. The farm had to have sales of a 

 specific product or a group of products amounting in value 

 of 50 percent or more of the total value of all products 

 sold during the census reference period to be classified 

 as a particular type of farm. 



The types of farms, together with the products (value 

 of sales representing 50 percent or more of the value of 

 agricultural products sold during the year) on which the 

 type of classification is based, are:

Sugarcane 

 Coffee 

 Tobacco 

 Grain and fari- 

 naceous crop 



Fruit and nut 



Livestock 

 Poultry 

 General crop 



Crop and

 including vegetables or ornamental and 

 flowering plants and lawn grass. 

 Crops as listed in the general crop type 

 together with the livestock, poultry, 

 and their products in the livestock type. 

 All farms not meeting any of the above 

 classifications. These include farms 

 with 50 percent or more of the total 

 value of agricultural products sold 

 coming from the sale of vegetables or 

 ornamental and flowering plants and 

 lawn grass. 



Other classifications — Also farms were classified by the 

 characteristics of the operator, such as residence, main 

 source of income, years operating present farm, educa- 

 tion, days worked off farm, and by the percent of income 

 received from farming. 



ENUMERATION PERIODS 



The enumeration periods for most items in the 1982 

 census were either the 1 2-month period from July 1 , 

 1 982, to June 30, 1 983, or as of July 1 , 1 983. Whenever 

 1978 is used in a table, title or boxhead, it refers to the 

 census period July 1 , 1 977, to June 30, 1 978, or as of 

 July 1, 1978. 



Data for the following items relate to the 12-month 

 period from July 1, 1982, to June 30, 1983, or to the 

 period of July 1, 1977, to June 30, 1978, when 

 applicable. 



a. Tenure. 



b. Land in farms. 



c. Agricultural products harvested and products sold. 



d. Livestock, poultry, and their products sold. 



e. Cultivated and/or improved pastures. 



f. Land use. 



g. Irrigation. 



h. Hired farm workers. 



i. Agricultural chemicals purchased and used. 



j. Selected farm production expenses. 



k. Farm-related income. 



Data for the following items pertain to July 1, 1983, 

 or July 1, 1978, when applicable. 



a. Inventory of livestock, poultry and hogs, on farms. 



b. Machinery, equipment, buildings, and facilities on 

 farms. 



c. Number of agregado and sharecropper families on 

 farms. 



Data for "Products for home consumption" for the 

 1 982 census pertain to the amount of products con- 

 sumed or given away during the last week before the 

 enumeration day July 1 , 1 983. In the 1 978 census, these 

 data pertain to the previous 1 2 months before the 

 enumeration day. 



USE OF SAMPLING AND STATISTICAL 

 ADJUSTMENT 



To reduce the respondent's burden, a sample of farms 

 was used to collect detailed economic information. 

 Statistical expansion procedures were then used to 

 expand the data to the municipio level. 



All expected farms were enumerated to obtain basic 

 farm information. In addition, sample questions (sections 

 21 through 25) were asked of all "large" farms and a sam- 

 ple of farms identified when the municipio was listed. 

 Other farms were selected into the sample with certainty 

 because they were expected to be large. A farm was con- 

 sidered large if its expected sales were greater than 

 $19,999 or its expected size was greater than 49 

 cuerdas. The definition of a large farm was the same for 

 each municipio. In addition to large farms, all farms in 

 municipios containing less than 250 farms in 1 978 were 

 required to complete sections 21 through 25. Farms in 

 municipios containing 250 farms or more in 1978 were 

 also required to complete sections 21 through 25 at a rate 

 of 1 in 5. 



After collection, the noncertainty samples were 

 stratified into 128 strata formed using 7 sales groups, 10 

 type-of-farm groups, and 3 size-of-farm groups. 



Sales 



$0 to $499 

 $500 to $1,199 

 $1,200 to $2,499 

 $2,500 to $4,999 

 $5,000 to $7,499 

 $7,500 to $9,999 

 $10,000 to $19,999 



Type of farm 



Sugar 



Tobacco 



Coffee 



Grain and fari- 

 naceous crop 



Fruit and nut 



Poultry 



Livestock 



General crop 



Crop and 

 livestock 



Miscellaneous 



Size of farm 



to 9 cuerdas 

 10 to 19 cuerdas 

 20 to 49 cuerdas 



This stratification was done to improve precision and 

 to reduce the bias in all estimates by weighting the 

 sample farms within stratum by the ratio of total farms 

 to sample farms. If the calculated weight was greater than
