Censuses

Dara has unique systems and procedures that allow us to read and capture full information on more than 25,000 census forms per hour and equipment. Capturing data and validating them in real time, personalizing imprinting a code that ensures its capture, classifying...

Our experience allows us to advise the government administration in the different types of censuses, population, students, agricultural, economic, etc.., Using the most appropriate technologies and rigorous planning in order to guarantee results within a specified time low technical and human resources costs.

Contact us and let us accompany you throughout the process: From initial analysis, planning, logistics, pollsters, and printed folders, transport, storage, maintenance, facilities and infrastructure, reading devices, data consolidation, exploitation and memories.

The image of the forms located on the bottom are actual census surveys Peru and Ireland that Dara has.
These forms designs respond to a treatment technology, based exclusively on mass image capture with traditional scanners, with little quality control or validation in real time. In a later process, OCR, the operator checks for a one manually.

National census require significant data processing centers with dozens of operators scanning and checking the polls. A large infrastructure with computers, scanners, servers, etc..
The duration of the process is important, measured in months. The main limitation is the quality of the results. The manual verification involves error rates can be important, especially when working long hours as a mechanical and routine activity.
The audit and analysis of errors is very difficult due to the lack of homogeneity of the samples and the diversity of the causes that can produce them.
This methodology involves accepting a priori error rate, with the highest security measures may be from 5 to 10% minimum.

To avoid the error rates of the traditional scanner-based systems and subsequent validation manual uses omr optical reading equipment. They reach values ​​close to 100% accuracy, with higher yields per team without data processing centers. The overall process is cheaper by not needing verifiers operators nor much infrastructure.
Instead greatest need printed census, with more leaves, having to encode the alphabet to avoid having to ocr.

An intermediate solution which puts quality of the results but using scanner technology for using ocr character recognition, is the hybrid of Lectodara use our equipment. The model LD 30000i to read more than 25,000 documents an hour.
A correct census survey design allows huge cost savings, results in record time.
Examples

The month of May 2008 concluded national census of Ecuador evaluating teachers. Our experience and technology have allowed do it in a minimum period of time with complete objectivity and rigor. A month later he was still hogging covers Ecuadorian national newspapers.

To the left of these lines an example of the impact it had on the media evaluation process for teachers in Ecuador. The event which took several covers dara commissioned in newspapers. You can read the articles by clicking on the image.
